Talk
Birkhoff-Bruhat Atlas and Total Positivity
- Kaitao Xie (The University of Hong Kong)
Abstract
A Birkhoff-Bruhat atlas locally models a stratified space by open Kazhdan-Lusztig varieties on a flag variety. In this talk, we will explore some applications of Birkhoff-Bruhat atlases to the study of total positivity. This is based on a joint work in progress with Huanchen Bao and Xuhua He.
