**2023년 9월 QSMS Monthly Seminar**

**Date:**9월 22일 금요일 오후 3시 ~ 4시**Place:**129동 101호**Speaker:**김명호**Title:**Quiver Hecke algebras and open Richardson varieties**Abstract**: The open Richardson variety $R_{w,v}$ is the intersection of a Schubert cell $S_w$ and an opposite Schubert cell $S_v$. We will review a monoidal category $\tilde C_{w,v}$ whose Grothendieck ring is isomorphic to the coordinate ring $C[R_{w,v}]$. It is a localization of a certain subcategory of the category of finite-dimensional modules over a quiver Hecke algebra. Several properties of the category will be discussed.
