Theta Positivity in Langrangian Grassmannian
- Kaitao Xie (The University of Hong Kong)
Abstract
Motivated by the study of higher Teichmuller theory, Guichard and Wienhard generalized Lusztig's notion of total positivity and introduce theta positivity. The totally nonnegative part of flag varieties has been studied extensively for many years, and many remarkable properties have been etablished. In this talk, I will discuss the analogues for a family of theta nonnegative part of Lagrangian Grassmannian.
