2023년 9월 QSMS  Monthly Seminar

 

  • Date:  9월 22일 금요일  오후 3시 ~ 4시
  • Place:  129동 101호
  • Speaker:  김명호 (경희대학교)
  • 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.
