SUMMARY:Lagrangian Floer Theory and Applications Program
DESCRIPTION:Lagrangian Floer theory and Applications Program \nDates: September 15–November 21\, 2026 \nLocation: CMSA G10\, 20 Garden St.\, Cambridge MA 02138 \nThis thematic program will focus on recent developments in Lagrangian Floer theory and applications.  These include the development of family Floer theory\, degeneration techniques\, Floer homotopy theory in the Lagrangian case\, Floer theory in prime characteristic\, and applications to problems in singularity theory\, geometry and dynamics. \nA one-week workshop will be held near the start of the program (September 28 – October 2\, 2026)\, with the same title as the thematic program. \nOrganizers: Denis Auroux (Harvard)\, Jonny Evans (Lancaster)\, and Chris Woodward (Rutgers) \n  \nTo express interest in attending the workshop or program\, and to apply for funding if available\, please fill out the form.  \nFunding from the National Science Foundation may be available for US-based graduate students and postdoctoral fellows. \n  \n \nimage: Water Sky Garden\, Vancouver\nDate: 31 January 2010\, 12:57:46\nSource: Studio Echelman\nAuthor: Peter Vanderwarker\, Studio Echelman \n

SUMMARY:CMSA Special Seminar: Deformations to the Complex Plane\, Novel Asymptotic Techniques\, and the Large t- Asymptotics of the Riemann Zeta Function
DESCRIPTION:CMSA Special Seminar \n \nSpeaker: Thanasis Fokas\, University of Cambridge \nTitle: Deformations to the Complex Plane\, Novel Asymptotic Techniques\, and the Large t-\nAsymptotics of the Riemann Zeta Function \nAbstract: The Unified Transform (also known as the Fokas method) is a powerful new method for\nsolving boundary value problems for linear and for integrable nonlinear PDEs. For linear\nPDEs\, the relevant transform is based on appropriate deformations of certain integrals from\nthe real line to the complex plane. After briefly reviewing this transform\, it will be shown\nthat combining this idea with novel asymptotic techniques has recently led to unexpected\nand exciting results regarding the large t-asymptotic analysis of the celebrated Riemann zeta\nfunction. The following two results will be discussed. First\, a simple formula will be\npresented for the difference of the functions defining the error terms in two historic\nproblems: in Atkinson’s formula and in the formula for the Dirichlet divisor problem; it will\nbe shown that this difference equals π/ 2 plus a function which is simply related to the\nsquare of the Riemann zeta function. Second\, a remarkable integral identity satisfied by the\nRiemann zeta function will be presented; this identity is obtained from an earlier identity\nderived by the speaker via contour deformation in the complex plane. Making crucial use of\nnovel asymptotic techniques obtained jointly with Jonatan Lenells\, the asymptotic analysis\nof this integral equation gives rise to an interesting identity satisfied\, for large t\, by a sum\ngeneralizing the Dirichlet divisor sum. Also\, and more importantly\, it gives rise to a specific\nintegral transform suitable for the large t-asymptotic analysis of the Riemann zeta function. \n
