    Symmetries and algebraicity in the flux landscape

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

    CMSA Member Seminar Speaker: Damian van de Heisteeg (Harvard CMSA) Title: Symmetries and algebraicity in the flux landscape Abstract: In this talk I consider potentials coming from fluxes in string theory. The minima of these potentials trace out special loci in the moduli space of Calabi-Yau manifolds. I discuss the structure that underlies these minima from a Hodge-theoretic […]

    Asymptotic decay for defocusing semilinear wave equations on Schwarzschild spacetimes

    Virtual

    General Relativity Seminar Speaker: He Mei, Shenzhen University Title: Asymptotic decay for defocusing semilinear wave equations on Schwarzschild spacetimes Abstract: In this talk, I will present a work on the long time dynamics of solutions to the defocusing semilinear wave equations on the Schwarzschild black hole spacetimes. For sufficiently smooth and localized initial data, we show that the […]

  • Computers and mathematics in partial differential equations: New developments and challenges

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

    https://youtu.be/JB2WqmpmTgk New Technologies in Mathematics Seminar Speaker: Javier Gomez Serrano, Brown University Title: Computers and mathematics in partial differential equations: new developments and challenges Abstract: In this talk I will address the interaction between traditional and more modern mathematics and how computers have helped over the last decade providing rigorous (computer-assisted) proofs in the context […]

  • Algebraic Geometry in String Theory Seminar

    Geometric origins of values of the Riemann Zeta functions at positive integers

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

    Algebraic Geometry in String Theory Seminar Speaker: Yan Zhou, Northeastern Title: Geometric origins of values of the Riemann Zeta functions at positive integers Abstract: Given a Fano manifold, Iritani proposed that the asymptotic behavior of solutions to the quantum differential equation of the Fano should be given by the so-called ‘Gamma class’ in its cohomology ring. […]

  • Quantum Matter in Mathematics and Physics Seminar

    Spontaneously Broken (-1)-form symmetries

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

    Quantum Matter in Mathematics and Physics Seminar Speaker: Motoo Suzuki (Harvard) Title: Spontaneously Broken (-1)-form symmetries Abstract: Spontaneous breaking of symmetries leads to universal phenomena. We extend this notion to (−1)-form U(1) symmetries. The spontaneous breaking is diagnosed by a dependence of the vacuum energy on a constant background field θ, which can be probed […]

    Integrability and Hidden Symmetries in Black Hole Dynamics

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

    CMSA Member Seminar Speaker: Uri Kol (Harvard CMSA) Title: Integrability and Hidden Symmetries in Black Hole Dynamics Abstract: The last decade has produced a number of remarkable discoveries, such as the first direct observation of gravitational waves by the LIGO/Virgo collaboration and the first black hole image taken by the Event Horizon Telescope. These discoveries mark the beginning of a […]

  • AQFT Seminar Series

    AQFT Lecture Series

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

    AQFT Lecture Series Speaker: Omer Offen (Brandeis) Title: Period integrals of automorphic forms and the residue method Abstract: I will discuss some aspects of period integrals of automorphic forms via examples. In particular, the residue method of Jacquet and Rallis and its recent application, joint with Friedberg and Ginzburg, to study new periods on the […]

  • Colloquium

    Factorization algebras in quite a lot of generality

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

    Colloquium Speaker: Clark Barwick, University of Edinburgh Title: Factorization algebras in quite a lot of generality Abstract: The objects of arithmetic geometry are not manifolds. Some concepts from differential geometry admit analogues in arithmetic, but they are not straightforward. How then can we hope to make precise sense of quantum field theories on these objects? […]

    On Axially Symmetric Perturbations of Kerr Black Hole Spacetimes

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

    https://youtu.be/G98ywTI82fg General Relativity Seminar Speaker: Nishanth Gudapati, Clark University Title: On Axially Symmetric Perturbations of Kerr Black Hole Spacetimes Abstract: The Kerr black hole stability problem is an important open problem in general relativity. In this talk, I will focus on the role of energy methods in the axisymmetric stability of Kerr black hole spacetimes. […]
