Event Series 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. […]

Event Series 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 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 […]

Event Series 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? […]

Event Series General Relativity Seminar

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. […]

Classifying curves on Fano varieties

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

Algebraic Geometry in String Theory Seminar Speaker: Brian Lehmann (Boston College) Title: Classifying curves on Fano varieties Abstract: How can we understand the set of curves on a Fano variety? One perspective is provided by Geometric Manin's Conjecture, a collection of conjectures with roots in arithmetic and topology.  While I will mention some recent progress, the main […]

Directed motion in active matter: Frictiotaxis and flocking

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

Active Matter Seminar Speaker: Ricard Alert, Max Planck Institute for the Physics of Complex Systems Title: Directed motion in active matter: Frictiotaxis and flocking Abstract: A key feature of active matter is its ability to move directionally, both as individual particles and collectively. I will discuss two examples of directed motion: one in cell migration, and one in collections of self-propelled colloids. […]
