报告人简介： Anne Moreau,法国里尔大学教授。她是法国国家研究项目the ANR project GeoLie (2015-2019)成员，同时也是法国研究项目the ANR project GERCHER (2010-2014)以及 GDR TLAG, of GDR GAGC and of GDRI Théorie de Représentations的成员。 报告内容： Just as nilpotent orbit closures in simple Lie algebra, nilpotent Slodowy slices play a significant role in representation theory and in the theory of symplectic singularities. In other direction, it is known that there appear as associated variety of W-algebras. It is also known that they appear as the Higgs branches of the Argyres-Douglas theories in 4d N = 2 SCFTs. In my talk, I will explain how these facts are related, and how we can use this to study collapsing levels for W-algebras, and related conjectures.This is based on a joint work in progress with Tomoyuki Arakawa. |
