Member Seminar Speaker: Sunghyuk Park, CMSA Title: Quantum topology from dynamics Abstract: Dynamics studies the long-term behavior of systems that evolve over time, such as the famous Lorenz system. Quantum topology, by contrast, studies knots and low-dimensional manifolds through invariants that are usually constructed using representation-theoretic tools. In this talk, I will explain how quantum invariants of […]
Member Seminar Speaker: Vasily Krylov Title: Higgs and Coulomb branches: Geometry and Representation Theory Abstract: Higgs and Coulomb branches of quiver gauge theories form two important families of Poisson varieties that are expected to be exchanged under so-called 3D mirror symmetry. Quantized Coulomb branches are associative algebras deforming the algebras of functions on Coulomb branches. They are […]

CMSA/Tsinghua Math-Science Literature Lecture Date: April 22, 2026 Time: 9:00 - 10:30 am ET Location: via Zoom Webinar Speaker: Nicolai Reshetikhin, Yau Mathematical Sciences Center, Tsinghua University Title: Asymptotic representation theory Abstract: Loosely speaking asymptotic representation theory studies representations of “large” groups or algebras. One of the first results in this direction is the study of […]

Algebra Seminar Speaker: Sudipta Das, Tata Institute of Fundamental Research Title: Transcendental Epsilon Multiplicity via Divisor Volumes Abstract: In this talk, our goal is to establish a structural bridge between asymptotic commutative algebra and transcendence theory to show that there exists an ideal in a Noetherian local ring whose epsilon multiplicity is transcendental. By equating the […]
