  • Abundance for mixed characteristic threefolds

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Member Seminar Speaker: Iacopo Brivio (CMSA) Title: Abundance for mixed characteristic threefolds Abstract: The Minimal Model Program (MMP) predicts that every algebraic variety X is birational to either a fibration in Fano varieties, or it admits a “minimal model” X', that is a birational model with nef canonical bundle K_X'. The Abundance conjecture predicts then […]

  • Twisted Tools for (Untwisted) Quantum Field Theory

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Mathematical Physics and Algebraic Geometry Speaker: Justin Kulp (Simons Center for Geometry and Physics) Title: Twisted Tools for (Untwisted) Quantum Field Theory Abstract: One of the most important properties of QFTs is that they can be deformed by "turning on interactions." Essentially every observable can be viewed as coupling the theory to some external system. Famously, adding […]

  • BPS Algebras in Landau-Ginzburg Models

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Speaker: Ahsan Khan (CMSA) Title: BPS Algebras in Landau-Ginzburg Models Abstract: The study of BPS states in supersymmetric quantum field theory has been a fruitful source of both mathematical and physical insights. In particular their study often leads to rich algebraic structures - from the "Algebra of the Infrared" of Gaiotto-Moore-Witten to the "Cohomological Hall […]

  • Combinatorics and geometry of the amplituhedron

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Colloquium Speaker: Lauren Williams, Harvard University Title: Combinatorics and geometry of the amplituhedron Abstract: The amplituhedron is a geometric object introduced by Arkani-Hamed and Trnka to compute scattering amplitudes in N=4 super Yang Mills theory. It generalizes interesting objects such as cyclic polytopes and the positive Grassmannian. It has connections to tropical geometry, cluster algebras, […]

  • Mathematics and Machine Learning Program

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Mathematics and Machine Learning Program Dates: September 3 - November 1, 2024 Location: Harvard CMSA, 20 Garden Street, Cambridge, MA 0213 Machine learning and AI are increasingly important tools in all fields of research. Recent milestones in machine learning for mathematics include data-driven discovery of theorems in knot theory and representation theory, the discovery and […]

  • Instanton in Lattice QCD from Higher Categories and Higher Anafunctors

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Speaker: Jing-Yuan Chen, Tsinghua University Title: Instanton in Lattice QCD from Higher Categories and Higher Anafunctors Abstract:  Putting continuum QFT (not just TQFT) on the lattice is important for both fundamental understandings and practical numerics. The traditional way of doing so, based on simple intuitions, however, does not admit natural definitions for general topological operators of continuous-valued […]

  • Compactified Hyperboloidal Evolution in Numerical Relativity

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Speaker: Shalabh Gautam, International Center for Theoretical Sciences, Tata Institute of Fundamental Research Title: Compactified Hyperboloidal Evolution in Numerical Relativity Abstract: In the field of numerical relativity, a major challenge is to incorporate future null infinity into the computational domain using a well-posed formulation. Achieving this goal would not only allow us to accurately simulate any […]
