SUMMARY:Morphogenesis: Geometry and Physics
DESCRIPTION:Just over a century ago\, the biologist\, mathematician and philologist D’Arcy Thompson wrote “On growth and form”. The book – a literary masterpiece – is a visionary synthesis of the geometric biology of form. It also served as a call for mathematical and physical approaches to understanding the evolution and development of shape. In the century since its publication\, we have seen a revolution in biology following the discovery of the genetic code\, which has uncovered the molecular and cellular basis for life\, combined with the ability to probe the chemical\, structural\, and dynamical nature of molecules\, cells\, tissues and organs across scales. In parallel\, we have seen a blossoming of our understanding of spatiotemporal patterning in physical systems\, and a gradual unveiling of the complexity of physical form. So\, how far are we from realizing the century-old vision that “Cell and tissue\, shell and bone\, leaf and flower\, are so many portions of matter\, and it is in obedience to the laws of physics that their particles have been moved\, moulded and conformed ?” \nTo address this requires an appreciation of the enormous ‘morphospace’ in terms of the potential shapes and sizes that living forms take\, using the language of mathematics. In parallel\, we need to consider the biological processes that determine form in mathematical terms is based on understanding how instabilities and patterns in physical systems might be harnessed by evolution. \nIn Fall 2018\, CMSA will focus on a program that aims at recent mathematical advances in describing shape using geometry and statistics in a biological context\, while also considering a range of physical theories that can predict biological shape at scales ranging from macromolecular assemblies to whole organ systems.\nThe first workshop will focus on the interface between Morphometrics and Mathematics\, while the second will focus on the interface between Morphogenesis and Physics.The workshop is organized by L. Mahadevan (Harvard)\, O. Pourquie (Harvard)\, A. Srivastava (Florida). \nAs part of the program on Mathematical Biology a workshop on Morphogenesis: Geometry and Physics will take place on December 3-5\, 2018.  The workshop will be held in room G10 of the CMSA\, located at 20 Garden Street\, Cambridge\, MA. \nVideos\nSpeakers:\n\nArkhat Abzhanov\, Imperial College\nYohanns Bellaiche\, Paris\nCheng Ming Chuong\, USC\nZev Gartner\, UCSF\nThomas Gregor\, Princeton\nDagmar Iber\, Zurich\nIan Jermyn\, Durham University\nRaymond Keller\, UVA\nAllon Klein\, HMS\nLisa Manning\, Syracuse\nCristina Marchetti\, UCSB\nSean Megason\, HMS\nElliot Meyerowitz\, Caltech\nMichel Milinkovitch\, Geneva\nLeonardo Morsut\, USC\nOlivier Pourquié\, HMS\nEric Siggia\, Rockefeller University\nBen Simons\, Cambridge\nSebastian Streichan\, UCSB\nAryeh Warmflash\, Rice

SUMMARY:Mathematical Biology
DESCRIPTION:During Academic year 2018-19\, the CMSA will be hosting a Program on Mathematical Biology. \nJust over a century ago\, the biologist\, mathematician and philologist D’Arcy Thompson wrote “On growth and form”. The book was a visionary synthesis of the geometric biology of form at the time. It also served as a call for mathematical and physical approaches to understanding the evolution and development of shape. \nIn the century since its publication\, we have seen a revolution in biology following the discovery of the genetic code\, which has uncovered the molecular and cellular basis for life\, combined with the ability to probe the chemical\, structural\, and dynamical nature of molecules\, cells\, tissues and organs across scales. In parallel\, we have seen a blossoming of our understanding of spatiotemporal patterning in physical systems\, and a gradual unveiling of the complexity of physical form. And in mathematics and computation\, there has been a revolution in terms of posing and solving problems at the intersection of computational geometry\, statistics and inference.  So\, how far are we from realizing a descriptive\, predictive and controllable theory of biological shape? \nIn Fall 2018\, CMSA will focus on a program that aims at recent mathematical advances in describing shape using geometry and statistics in a biological context\, while also considering a range of physical theories that can predict biological shape at scales ranging from macromolecular assemblies to whole organ systems \nThe CMSA will be hosting three workshops as part of this program. The Workshop on Morphometrics\, Morphogenesis and Mathematics will take place on October 22-26.  \nA workshop on Morphogenesis: Geometry and Physics will take place on December 3-6\, 2018. \nA workshop on Invariance and Geometry in Sensation\, Action and Cognition will take place on April 15-17\, 2019.

SUMMARY:Workshop on Morphometrics\, Morphogenesis and Mathematics
DESCRIPTION:In Fall 2018\, the CMSA will host a Program on Mathematical Biology\, which aims to describe recent mathematical advances in using geometry and statistics in a biological context\, while also considering a range of physical theories that can predict biological shape at scales ranging from macromolecular assemblies to whole organ systems. \nThe plethora of natural shapes that surround us at every scale is both bewildering and astounding – from the electron micrograph of a polyhedral virus\, to the branching pattern of a gnarled tree to the convolutions in the brain. Even at the human scale\, the   shapes seen in a garden at the scale of a pollen grain\, a seed\, a sapling\, a root\, a flower or leaf are so numerous that “it is enough to drive the sanest man mad\,” wrote Darwin. Can we classify these shapes and understand their origins quantitatively? \nIn biology\, there is growing interest in and ability to quantify growth and form in the context of the size and shape of bacteria and other protists\, to understand how polymeric assemblies grow and shrink (in the cytoskeleton)\, and how cells divide\, change size and shape\, and move to organize tissues\, change their topology and geometry\, and link multiple scales and connect biochemical to mechanical aspects of these problems\, all in a self-regulated setting. \nTo understand these questions\, we need to describe shape (biomathematics)\, predict shape (biophysics)\, and design shape (bioengineering). \nFor example\, in mathematics there are some beautiful links to Nash’s embedding theorem\,  connections to quasi-conformal geometry\, Ricci flows and geometric PDE\, to Gromov’s h principle\, to geometrical singularities and singular geometries\, discrete and computational differential geometry\, to stochastic geometry and shape characterization (a la Grenander\, Mumford etc.). A nice question here is to use the large datasets (in 4D) and analyze them using ideas from statistical geometry (a la Taylor\, Adler) to look for similarities and differences across species during development\, and across evolution. \nIn physics\, there are questions of generalizing classical theories to include activity\, break the usual Galilean invariance\, as well as isotropy\, frame indifference\, homogeneity\, and create both agent (cell)-based and continuum theories for ordered\, active machines\, linking statistical to continuum mechanics\, and understanding the instabilities and patterns that arise. Active generalizations of liquid crystals\, polar materials\, polymers etc. are only just beginning to be explored and there are some nice physical analogs of biological growth/form that are yet to be studied. \nThe CMSA will be hosting a Workshop on Morphometrics\, Morphogenesis and Mathematics from October 22-24\, 2018 at the Center of Mathematical Sciences and Applications\, located at 20 Garden Street\, Cambridge\, MA. \nThe workshop is organized by L. Mahadevan (Harvard)\, O. Pourquie (Harvard)\, A. Srivastava (Florida). \nVideos of the talks\nConfirmed Speakers:\n\nArkhat Abzhanov\, Imperial College\nSiobhan Braybrook\, UCLA\nCassandra Extavour\, Harvard\nAnjali Goswami\, University College London\nDavid Gu\, Stony Brook\nJukka Jernvall\, Helsinki\nEric Klassen\, Florida State\nSayan Mukherjee\, Duke\nPeter Olver\, U Minnesota\nNipam Patel\, Berkeley\nStephanie Pierce\, Harvard\nKaren Sears\, UCLA\nAlain Trouve\, ENS-Cachan\, France\nLaurent Younes\, Johns Hopkins

SUMMARY:Simons Collaboration on Homological Mirror Symmetry
DESCRIPTION:The Simons Collaboration on Homological Mirror Symmetry brings together a group of leading mathematicians working towards the goal of proving Homological Mirror Symmetry (HMS) in full generality\, and fully exploring its applications. This program is funded by the Simons Foundation. \nMirror symmetry\, which emerged in the late 1980s as an unexpected physical duality between quantum field theories\, has been a major source of progress in mathematics. At the 1994 ICM\, Kontsevich reinterpreted mirror symmetry as a deep categorical duality: the HMS conjecture states that the derived category of coherent sheaves of a smooth projective variety is equivalent to the Fukaya category of a mirror symplectic manifold (or Landau-Ginzburg model). \nWe envision that our goal of proving HMS in full generality can be accomplished by combining three main viewpoints: \n\ncategorical algebraic geometry and non-commutative (nc) spaces: in this language\, homological mirror symmetry is the statement that the same nc-spaces can arise either from algebraic geometry or from symplectic geometry.\nthe Strominger-Yau-Zaslow (SYZ) approach\, which provides a global geometric prescription for the construction of mirror pairs.\nLagrangian Floer theory and family Floer cohomology\, which provide a concrete path from symplectic geometry near a given Lagrangian submanifold to an open domain in a mirror analytic space.\n\nThe Center of Mathematical Sciences and Applications is hosting the following short-term visitors for an HMS focused semester: \n\nJacob Bourjaily (Neils Bohr Institute)  4/1/2018 – 4/14/2018\nColin Diemer (IHES)  2/25/2018 – 3/10/2018\nCharles Doran (University of Alberta) 5/13/2018 – 5/25/2018\nBaohua Fu (Chinese Academy of Sciences)  4/15/2018 – 4/28/2018\nAndrew Harder (University of Miami)  4/15/2018 – 4/28/2018\nShinobu Hosono (Gakushuin University) 2/25/2018 – 3/10/2018\nAdam Jacob (UC Davis) 3/5/2018 – 3/16/2018\nTsung-Ju Lee (National Taiwan University) 4/18/2018 – 5/13/2018\nIvan Loseu (Northeastern University) 1/21/2018 – 2/3/2018\nCheuk-Yu Mak (Cambridge University) 4/1/2018 – 4/15/2018\nDaniel Pomerleano (Imperial College) 3/19/2018 – 3/23/2018\nMauricio Romo (Tsinghua University) 4/1/2018 – 4/18/ 2018\nEmanuel Scheidegger (Albert Ludwigs University of Freiburg) 2/22/2018 – 3/22/2018\nDmytro Shklyarov (Technische Universität Chemnitz) 3/4/2018 – 3/17/2018\nAlan Thompson (University of Cambridge) 4/15/2018 – 4/21/2018\nWeiwei Wu (University of Georgia) 4/27/2018 – 5/6/2018\nMatt Young (Chinese University of Hong Kong) 1/15/2018 – 2/9/2018\nJeng-Daw Yu (National Taiwan University) 4/2/2018 – 4/6/2018\nMinxian Zhu (Yau Mathematical Sciences Center\, Tsinghua University) 1/ 22/2018 – 2/25/2018\n\nAs part of their CMSA visitation\, HMS focused visitors will be giving lectures on various topics related to Homological Mirror Symmetry throughout the Spring 2018 Semester.  Click here for information. \n\n\nThe Collaboration will include two workshops hosted by The Center. The workshops will take place January 10-13\, 2018  and April 5-7\, 2018 at CMSA. Click here for more information.

SUMMARY:The Simons Collaboration Program in Homological Mirror Symmetry
DESCRIPTION:The Simons Collaboration program in Homological Mirror Symmetry at Harvard CMSA and Brandeis University is part of the bigger Simons collaboration program on Homological mirror symmetry (https://schms.math.berkeley.edu) which brings to CMSA experts on algebraic geometry\, Symplectic geometry\, Arithmetic geometry\, Quantum topology and mathematical aspects of high energy physics\, specially string theory with the goal of proving the homological mirror symmetry conjecture (HMS) in full generality and explore its applications. Mirror symmetry\, which emerged in the late 1980s as an unexpected physical duality between quantum field theories\, has been a major source of progress in mathematics. At the 1994 ICM\, Kontsevich reinterpreted mirror symmetry as a deep categorical duality: the HMS conjecture states that the derived category of coherent sheaves of a smooth projective variety is equivalent to the Fukaya category of a mirror symplectic manifold (or Landau-Ginzburg model). We are happy to announce that the Simons Foundation has agreed to renew funding for the HMS collaboration program for three additional years. \nA brief induction of the Brandeis-Harvard CMSA HMS/SYZ research agenda and team members are as follows: \n\nDirectors: \n\nShing-Tung Yau (Harvard University) \nBorn in Canton\, China\, in 1949\, S.-T. Yau grew up in Hong Kong\, and studied in the Chinese University of Hong Kong from 1966 to 1969. He did his PhD at UC Berkeley from 1969 to 1971\, as a student of S.S. Chern. He spent a year as a postdoc at the Institute for Advanced Study in Princeton\, and a year as assistant professor at SUNY at Stony Brook. He joined the faculty at Stanford in 1973. On a Sloan Fellowship\, he spent a semester at the Courant Institute in 1975. He visited UCLA the following year\, and was offered a professorship at UC Berkeley in 1977. He was there for a year\, before returning to Stanford. He was a plenary speaker at the 1978 ICM in Helsinki. The following year\, he became a faculty member at the IAS in Princeton. He moved to UCSD in 1984. Yau came to Harvard in 1987\, and was appointed the Higgins Professor of Mathematics in 1997. He has been at Harvard ever since. Yau has received numerous prestigious awards and honors throughout his career. He was named a California Scientist of the Year in 1979. In 1981\, he received a Oswald Veblen Prize in Geometry and a John J. Carty Award for the Advancement of Science\, and was elected a member of the US National Academy of Sciences. In 1982\, he received a Fields Medal for “his contributions to partial differential equations\, to the Calabi conjecture in algebraic geometry\, to the positive mass conjecture of general relativity theory\, and to real and complex MongeAmpre equations”. He was named Science Digest\, America’s 100 Brightest Scientists under 40\, in 1984. In 1991\, he received a Humboldt Research Award from the Alexander von Humboldt Foundation in Germany. He was awarded a Crafoord Prize in 1994\, a US National Medal of Science in 1997\, and a China International Scientific and Technological Cooperation Award\, for “his outstanding contribution to PRC in aspects of making progress in sciences and technology\, training researchers” in 2003. In 2010\, he received a Wolf Prize in Mathematics\, for “his work in geometric analysis and mathematical physics”. Yau has also received a number of research fellowships\, which include a Sloan Fellowship in 1975-1976\, a Guggenheim Fellowship in 1982\, and a MacArthur Fellowship in 1984-1985. Yau’s research interests include differential and algebraic geometry\, topology\, and mathematical physics. As a graduate student\, he started to work on geometry of manifolds with negative curvature. He later became interested in developing the subject of geometric analysis\, and applying the theory of nonlinear partial differential equations to solve problems in geometry\, topology\, and physics. His work in this direction include constructions of minimal submanifolds\, harmonic maps\, and canonical metrics on manifolds. The most notable\, and probably the most influential of this\, was his solution of the Calabi conjecture on Ricci flat metrics\, and the existence of Kahler-Einstein metrics. He has also succeeded in applying his theory to solve a number of outstanding conjectures in algebraic geometry\, including Chern number inequalities\, and the rigidity of complex structures of complex projective spaces. Yau’s solution to the Calabi conjecture has been remarkably influential in mathematical physics over the last 30 years\, through the creation of the theory of Calabi-Yau manifolds\, a theory central to mirror symmetry. He and a team of outstanding mathematicians trained by him\, have developed many important tools and concepts in CY geometry and mirror symmetry\, which have led to significant progress in deformation theory\, and on outstanding problems in enumerative geometry. Lian\, Yau and his postdocs have developed a systematic approach to study and compute period integrals of CY and general type manifolds. Lian\, Liu and Yau (independently by Givental) gave a proof of the counting formula of Candelas et al for worldsheet instantons on the quintic threefold. In the course of understanding mirror symmetry\, Strominger\, Yau\, and Zaslow proposed a new geometric construction of mirror symmetry\, now known as the SYZ construction. This has inspired a rapid development in CY geometry over the last two decades. In addition to CY geometry and mirror symmetry\, Yau has done influential work on nonlinear partial differential equations\, generalized geometry\, Kahler geometry\, and general relativity. His proof of positive mass conjecture is a widely regarded as a cornerstone in the classical theory of general relativity. In addition to publishing well over 350 research papers\, Yau has trained more than 60 PhD students in a broad range of fields\, and mentored dozens of postdoctoral fellows over the last 40 years. \n\nProfessor Bong Lian (Brandeis University) \nBorn in Malaysia in 1962\, Bong Lian completed his PhD in physics at Yale University under the direction of G. Zuckerman in 1991. He joined the permanent faculty at Brandeis University in 1995\, and has remained there since. Between 1995 and 2013\, he had had visiting research positions at numerous places\, including the National University of Taiwan\, Harvard University\, and Tsinghua University. Lian received a J.S. Guggenheim Fellowship in 2003. He was awarded a Chern Prize at the ICCM in Taipei in 2013\, for his “influential and fundamental contributions in mathematical physics\, in particular in the theory of vertex algebras and mirror symmetry.” He has also been co-Director\, since 2014\, of the Tsinghua Mathcamp\, a summer outreach program launched by him and Yau for mathematically talented teenagers in China. Since 2008\, Lian has been the President of the International Science Foundation of Cambridge\, a non-profit whose stated mission is “to provide financial and logistical support to scholars and universities\, to promote basic research and education in mathematical sciences\, especially in the Far East.” Over the last 20 years\, he has mentored a number of postdocs and PhD students. His research has been supported by an NSF Focused Research Grant since 2009. Published in well over 60 papers over 25 years\, Lian’s mathematical work lies in the interface between representation theory\, Calabi-Yau geometry\, and string theory. Beginning in the late 80’s\, Lian\, jointly with Zuckerman\, developed the theory of semi-infinite cohomology and applied it to problems in string theory. In 1994\, he constructed a new invariant (now known as the Lian- Zuckerman algebra) of a topological vertex algebra\, and conjectured the first example of a G algebra in vertex algebra theory. The invariant has later inspired a new construction of quantum groups by I. Frenkel and A. Zeitlin\, as semi-infinite cohomology of braided vertex algebras\, and led to a more recent discovery of new relationships between Courant algebroids\, A-algebras\, operads\, and deformation theory of BV algebras. In 2010\, he and his students Linshaw and Song developed important applications of vertex algebras in equivariant topology. Lian’s work in CY geometry and mirror symmetry began in early 90’s. Using a characteristic p version of higher order Schwarzian equations\, Lian and Yau gave an elementary proof that the instanton formula of Candelas et al implies Clemens’s divisibility conjecture for the quintic threefold\, for infinitely many degrees. In 1996\, Lian (jointly with Hosono and Yau) answered the so-called Large Complex Structure Limit problem in the affirmative in many important cases. Around the same year\, they announced their hyperplane conjecture\, which gives a general formula for period integrals for a large class of CY manifolds\, extending the formula of Candelas et al. Soon after\, Lian\, Liu and Yau (independently by Givental) gave a proof of the counting formula. In 2003\, inspired by mirror symmetry\, Lian (jointly with Hosono\, Oguiso and Yau) discovered an explicit counting formula for Fourier-Mukai partners\, and settled an old problem of Shioda on abelian and K3 surfaces. Between 2009 and 2014\, Lian (jointly with Bloch\, Chen\, Huang\, Song\, Srinivas\, Yau\, and Zhu) developed an entirely new approach to study the so-called Riemann-Hilbert problem for period integrals of CY manifolds\, and extended it to general type manifolds. The approach leads to an explicit description of differential systems for period integrals with many applications. In particular\, he answered an old question in physics on the completeness of Picard-Fuchs systems\, and constructed new differential zeros of hypergeometric functions. \n\nDenis Auroux (Harvard University) \nDenis Auroux’s research concerns symplectic geometry and its applications to mirror symmetry. While his early work primarily concerned the topology of symplectic 4-manifolds\, over the past decade Auroux has obtained pioneering results on homological mirror symmetry outside of the Calabi-Yau setting (for Fano varieties\, open Riemann surfaces\, etc.)\, and developed an extension of the SYZ approach to non-Calabi-Yau spaces.After obtaining his PhD in 1999 from Ecole Polytechnique (France)\, Auroux was employed as Chargé de Recherche at CNRS and CLE Moore Instructor at MIT\, before joining the faculty at MIT in 2002 (as Assistant Professor from 2002 to 2004\, and as Associate Professor from 2004 to 2009\, with tenure starting in 2006). He then moved to UC Berkeley as a Full Professor in 2009.\nAuroux has published over 30 peer-reviewed articles\, including several in top journals\, and given 260 invited presentations about his work. He received an Alfred P. Sloan Research Fellowship in 2005\, was an invited speaker at the 2010 International Congress of Mathematicians\, and in 2014 he was one of the two inaugural recipients of the Poincaré Chair at IHP. He has supervised 10 PhD dissertations\, won teaching awards at MIT and Berkeley\, and participated in the organization of over 20 workshops and conferences in symplectic geometry and mirror symmetry.\n\n \n\n\n\nSenior Personnel: \n\nArtan Sheshmani (Harvard CMSA) \nArtan Sheshmani’s research is focused on enumerative algebraic geometry and mathematical aspects of string theory. He is interested in applying techniques in algebraic geometry\, such as\, intersection theory\, derived category theory\, and derived algebraic geometry to construct and compute the deformation invariants of algebraic varieties\, in particular Gromov-Witten (GW) or Donaldson-Thomas (DT) invariants. In the past Professor Sheshmani has worked on proving modularity property of certain DT invariants of K3-fibered threefolds (as well as their closely related Pandharipande-Thomas (PT) invariants)\, local surface threefolds\, and general complete intersection Calabi-Yau threefolds. The modularity of DT/PT invariants in this context is predicted in a famous conjecture of  string theory called S-duality modularity conjecture\, and his joint work has provided the proof to some cases of it\, using degenerations\, virtual localizations\, as well as wallcrossing techniques. Recently\, Sheshmani has focused on proving a series of dualities relating the various enumerative invariants over threefolds\, notably the GW invariants and invariants that arise in topological gauge theory. In particular in his joint work with Gholampour\, Gukov\, Liu\, Yau he studied DT gauge theory and its reductions to D=4 and D=2 which are equivalent to local theory of surfaces in Calabi-Yau threefolds. Moreover\, in a recent joint work with Yau and Diaconescu\, he has studied the construction and computation of DT invariants of Calabi-Yau fourfolds via a suitable derived categorical reduction of the theory to the DT theory of threefolds. Currently Sheshmani is interested in a wide range of problems in enumerative geometry of CY varieties in dimensions 3\,4\,5. \nArtan has received his PhD and Master’s degrees in pure mathematics under Sheldon Katz and Thomas Nevins from the University of Illinois at Urbana Champaign (USA) in 2011 and 2008 respectively. He holds a Master’s degree in Solid Mechanics (2004) and two Bachelor’s degrees\, in Mechanical Engineering and Civil Engineering from the Sharif University of Technology\, Tehran\, Iran.  Artan has been a tenured Associate Professor of Mathematics with joint affiliation at Harvard CMSA and center for Quantum Geometry of Moduli Spaces (QGM)\, since 2016. Before that he has held visiting Associate Professor and visiting Assistant Professor positions at MIT. \nAn Huang (Brandeis University) \nThe research of An Huang since 2011 has been focused on the interplay between algebraic geometry\, the theory of special functions and mirror symmetry. With S. Bloch\, B. Lian\, V. Srinivas\, S.-T. Yau\, X. Zhu\, he has developed the theory of tautological systems\, and has applied it to settle several important problems concerning period integrals in relation to mirror symmetry. With B. Lian and X. Zhu\, he has given a precise geometric interpretation of all solutions to GKZ systems associated to Calabi-Yau hypersurfaces in smooth Fano toric varieties. With B. Lian\, S.-T. Yau\, and C.-L. Yu\, he has proved a conjecture of Vlasenko concerning an explicit formula for unit roots of the zeta functions of hypersurfaces\, and has further related these roots to p-adic interpolations of complex period integrals. Beginning in 2018\, with B. Stoica and S.-T. Yau\, he has initiated the study of p-adic strings in curved spacetime\, and showed that general relativity is a consequence of the self-consistency of quantum p-adic strings. One of the goals of this study is to understand p-adic A and B models. \nAn Huang received his PhD in Mathematics from the University of California at Berkeley in 2011. He was a postdoctoral fellow at the Harvard University Mathematics Department\, and joined Brandeis University as an Assistant Professor in Mathematics in 2016.\n\n\n\nSiu Cheong Lau (Boston University) \nThe research interest of Siu Cheong Lau lies in SYZ mirror symmetry\, symplectic and algebraic geometry.  His thesis work has successfully constructed the SYZ mirrors for all toric Calabi-Yau manifolds based on quantum corrections by open Gromov-Witten invariants and their wall-crossing phenomenon.  In collaboration with N.C. Leung\, H.H. Tseng and K. Chan\, he derived explicit formulas for the open Gromov-Witten invariants for semi-Fano toric manifolds which have an obstructed moduli theory.  It has a beautiful relation with mirror maps and Seidel representations.   Recently he works on a local-to-global approach to SYZ mirror symmetry.  In joint works with C.H. Cho and H. Hong\, he developed a noncommutative local mirror construction for immersed Lagrangians\, and a natural gluing method to construct global mirrors.  The construction has been realized in various types of geometries including orbifolds\, focus-focus singularities and pair-of-pants decompositions of Riemann surfaces. \nSiu-Cheong Lau has received the Doctoral Thesis Gold Award (2012) and the Best Paper Silver Award (2017) at the International Congress of Chinese Mathematicians.  He was awarded the Simons Collaboration Grant in 2018.  He received a Certificate of Teaching Excellence from Harvard University in 2014. \n\nAffiliates: \n\nNetanel Rubin-Blaier (Cambridge)\nKwokwai Chan (Chinese University of Hong Kong)\nMandy Cheung (Harvard University\, BP)\nChuck Doran (University of Alberta)\nHansol Hong (Yonsei University)\nShinobu Hosono (Gakushuin University\, Japan)\nConan Leung (Chinese University of Hong Kong)\nYu-Shen Lin (Boston University)\nHossein Movassati (IMPA Brazil)\nArnav Tripathhy (Harvard University\, BP)\n\n  \nPostdocs: \n\nDennis Borisov\nTsung-Ju Lee\nDingxin Zhang\nJingyu Zhao\nYang Zhou\n\n  \nTo learn about previous programming as part of the Simons Collaboration\, click here.

SUMMARY:Nonlinear Equations Program
DESCRIPTION:  \nMost physical phenomena\, from the gravitating universe to fluid dynamics\, are modeled on nonlinear differential equations. The subject also makes close connections with other branches of mathematics. In particular\, some of the deepest results in complex geometry and topology were obtained through solutions of nonlinear equations. \nThe subject underwent rapid developments in the last century and foundational results were established. Compared to linear equations\, the difficulty of solving nonlinear equations is of a different order of magnitude and the methods employed in solving them are also much more diversified. To this date\, it is an active field with recent exciting discoveries and renewed interests\, and several long standing problems seem to be within reach. The special year aims to spur activity in this subject\, to provide a natural setting for the most cutting edge results to be communicated\, and to facilitate interaction among researchers of different backgrounds. \nDuring the year\, there will be two weekly seminar programs.  Each program participants will be asked to give a talk on geometric analysis\, or the evolution of equations\, hyperbolic equations\, and fluid dynamics.    \nSeminar on Geometric Analysis \nSeminar on Evolution Equations \nSeminar on General Relativity \nConcluding Conference on Nonlinear Equations Program \nMini-School on Nonlinear Equations\, Dec. 2016 \nHere is a partial list of the mathematicians who have indicated that they will attend part or all of this special program \n\n\n\n\n\n\nName\nHome Institution\nTentative Visiting Dates\n\n\n\n\nStefano Bianchini\nSISSA\n04/01/2016 – 05/31/2016\n\n\nLydia Bieri\nUniversity of Michigan\n02/01/2016 – 04/30/2016\n\n\nAlbert Chau\nUniversity of British Columbia\n02/26/2016 – 05/26/2016\n\n\nBinglong Chen\nSun Yat-sen University\n09/01/2015 – 11/30/2015\n\n\nQingtao Chen\nETHZ (Swiss Federal Institute of Technology in Zurich)\n03/17/2016 – 04/04/2016\n\n\nPiotr Chrusciel\nUniversity of Vienna\n03/01/2016 – 05/30/2016\n\n\nFernando Coda Marques\nPrinceton University\n04/25/2016 – 04/29/2016 05/23/2016 – 05/27/2016\n\n\nMihalis Dafermos\nPrinceton University\n04/01/2016 – 04/30/2016\n\n\nCamillo De Lellis\nUniversity of Zurich\n02/01/2016 – 4/30/2016\n\n\nMichael Eichmair\nUniversity of Vienna\n03/21/2016 – 04/01/2016\n\n\nFelix Finster\nUniversitat Regensburg\n09/20/2015 – 10/20/2015 03/20/2016 – 04/20/2016\n\n\nXianfeng David Gu\nSUNY at Stony Brook\n04/01/2016 – 04/30/2016\n\n\nZheng-Cheng Gu\nPerimeter Institute for Theoretical Physics\n08/15/2015 – 09/15/2015\n\n\nPengfei Guan\nMcGill University\n10/10/2015 – 10/17/2015\n\n\nXiaoli Han\nTsinghua University\n01/20/2016 – 04/19/2016\n\n\nThomas Hou\nCalifornia Institute of Technology\n11/01/2016 – 11/30/2016\n\n\nFeimin Huang\nChinese Academy of Sciences\n02/15/2016 – 04/15/2016\n\n\nXiangdi Huang\nChinese Academy of Sciences\n09/10/2015 – 12/10/2015\n\n\nTom Ilmanen\nETH Zurich\n10/19/2015 – 12/18/2015\n\n\nNiky Kamran\nMcGill Univeristy\n04/04/2016 – 04/08/2016\n\n\nNicolai Krylov\nUniversity of Minnesota\n11/01/2015 – 11/30/2015\n\n\nJunbin Li\nSun Yat-sen University\n02/01/2016 – 04/30/2016\n\n\nYong Lin\nRenmin University of China\n02/01/2016 – 03/31/2016\n\n\nAndre Neves\nImperial College London\n4/25/2016 – 4/29/2016; 5/23/2016 – 5/27/2016\n\n\nDuong H.

SUMMARY:GAMES ON HETEROGENEOUS GRAPHS
DESCRIPTION:A major challenge in evolutionary biology is to understand how spatial population structure affects the evolution of social behaviors such as\ncooperation. This question can be investigated mathematically by studying evolutionary processes on graphs. Individuals occupy vertices and interact with neighbors according to a matrix game. Births and deaths occur stochastically according to an update rule. Previously\, full mathematical results have only been obtained for graphs with strong symmetry properties. Our group is working to extend these results to certain classes of asymmetric graphs\, using tools such as random walk theory and harmonic analysis. \n \n\n\n  \nHere is a list of the scholars participating in this program. \n\n\n\n\nName\n\n\n\n\nShing-Tung Yau\n\n\nMartin Nowak\n\n\nBen Adlam\n\n\nBen Allen\n\n\nYu-Ting Chen\n\n\nAn Huang\n\n\nGabor Lippner

SUMMARY:MATH-PHYSICS PROGRAM
DESCRIPTION:In the past thirty years there have been deep interactions between mathematics and theoretical physics which have tremendously enhanced both subjects. The focal points of these interactions include string theory\, general relativity\, and quantum many-body theory. \nString theory has been at the center of the ongoing effort to uncover the fundamental principles of nature and in particular to unify Einstein’s geometric theory of gravity with quantum theory. The development of this field has sparked a historically unprecedented synergy between mathematics and physics. Progress at the forefront of theoretical physics has relied crucially on very recent developments in pure mathematics. At the same time insights from physics have led to both new branches of pure mathematics as well as dramatic progress in old branches. \nSeveral examples from the recent past exemplifying this synergy include the prediction from string theory of mirror symmetry\, a highly unexpected mathematical equivalence between distinct pairs of Calabi-Yau manifolds. This fueled exciting developments in algebraic\, enumerative and symplectic geometry. At the same time the realization of string theory as a phenomenologically viable physical theory depends crucially on detailed mathematical properties of these manifolds. In Einstein’s theory of general relativity the proofs of the positive energy theorem and the stability of flat spacetime were accompanied by fundamental new results in functional analysis\, differential geometry and minimal surface theory. In the coming decades we expect many more important discoveries to arise from the interface of mathematics and physics. The Cheng Fund will foster these efforts. \n\n\nHere is a partial list of the mathematicians who have indicated that they will attend part or all of this special program \n\n\n\n\nName\nTentative Visiting Dates\n\n\n\n\nPo-Ning Chen\n2/1/15-4/30/15\n\n\nHong-Jian He\n3/5/15-5/5/15\n\n\nMonica Guica\n12/1/14-3/15/15\n\n\nAmer Iqbal\n1/8/15-4/8/15\n\n\nSuvrat Raju\n2/25/15-5/25/15\n\n\nMithat Ünsal\n9/1/15-12/31/15

SUMMARY:Random Matrix Program
DESCRIPTION:Large random matrices provide some of the simplest models for large\, strongly correlated quantum systems. The statistics of the energy levels of ensembles of such systems are expected to exhibit universality\, in the sense that they depend only on the symmetry class of the system. Recent advances have enabled a rigorous understanding of universality in the case of orthogonal\, Hermitian\, or symplectic matrices with independent entries\, resolving a conjecture of Wigner-Dyson-Mehta dating back 50 years. These new developments have exploited techniques from a wide range of mathematical areas in addition to probability\, including combinatorics\, partial differential equations\, and hydrodynamic limits. It is hoped that these new techniques will be useful in the analysis of universal behaviour in matrix ensembles with more complicated structure such as random regular graph models\, or 2D matrix ensembles\, as well as more physically relevant systems such as band matrices and random Schroedinger-type Hamiltonians. For some of these models\, results in the direction of universality have already been obtained. \n\n\nHere is a partial list of the mathematicians who are participating in this program. \n\n\n\n\nName\n\n\n\n\nHorng-Tzer Yau\n\n\nQian Lin\n\n\nRoland Bauerschmidt\n\n\nMiika Nikula\n\n\nYu-Ting Chen\n\n\nBen Landon\n\n\nYuchen Pei\n\n\nPhilippe Sosoe
