SUMMARY:Abelian gauge fields and duality
DESCRIPTION:Joint Math/CMSA Geometry and Quantum Theory Seminar \nSpeaker: Dan Freed\, Harvard Math & CMSA \nTitle: Abelian gauge fields and duality \nAbstract: Motivated by the new paper arXiv:2603.19161\, I will give a general talk about abelian gauge fields\, including duality. I will start with classical Maxwell theory\, then discuss various “finite” examples\, the typical p-form abelian gauge field\, and some exotic examples such as Ramond–Ramond fields and the B-field in superstring theory. I will then get to the new paper and\, time permitting\, will suggest a very general framework that covers all examples. \n

SUMMARY:CMSA/Tsinghua Math-Science Literature Lecture: Nicolai Reshetikhin (Tsinghua): Asymptotic representation theory
DESCRIPTION:CMSA/Tsinghua Math-Science Literature Lecture \nDate: April 22\, 2026 \nTime: 9:00 – 10:30 am ET \nLocation: via Zoom Webinar \nSpeaker: Nicolai Reshetikhin\, Yau Mathematical Sciences Center\, Tsinghua University \nTitle: Asymptotic representation theory \nAbstract: Loosely speaking asymptotic representation theory studies representations of “large” groups or algebras. One of the first results in this direction is the study of Plancherel measures on the symmetric group $S_N$ in the limit $N\to \infty$ by Vershik and Kerov and Logan and Shepp. The first part of the talk will be an overview of results on statistics of irreducible representations in large tensor products. Then we focus on more modern results on statistics of tilting and projective modules in large tensor products and on how some problems in asymptotic representation theory are related to dimer models in statistical mechanics. \nRegistration is required for the Zoom link.\nZoom webinar registration link \n  \n\nBeginning in Spring 2020\, the CMSA began hosting a lecture series on literature in the mathematical sciences\, with a focus on significant developments in mathematics that have influenced the discipline\, and the lifetime accomplishments of significant scholars. \n  \n
