Morse theory for sheaves of categories

报告人：David Nadler,

摘要： I will take the opportunity to describe some arguments appearing in joint work with Penghui Li and Zhiwei Yun on the cocenter of the affine Hecke category. We use some elementary aspects of Morse theory for sheaves of categories on a manifold. I will des

BPS state counting with Exponential networks

报告人：Sibasish Banerjee, IHES

摘要： I will describe the framework of Exponential Networks for computing the BPS spectrum of M-theory on a local Calabi-Yau threefold times R4×S1. Exponential networks define the counting of special Lagrangians in the mirror Calabi-Yau threefold. Therefor

报告人：Pietro Longhi,

摘要：The framework of spectral networks was introduced in physics as a way to compute BPS states of 4d N=2 gauge theories.
