Speaker: 覃帆,清华大学数学科学中心 Inviter: 晨兴中心 Title: From graded quiver varieties to quantum cluster algebras and quantum groups Time & Venue: 2013.3.19 2:30pm C410 Abstract: Inspired by a previous work of Nakajima, we consider perverse sheaves over acyclic graded quiver varieties and study the Fourier-Sato-Deligne transform from a representation theoretic point of view. We obtain that all quantum cluster monomials in our setting belong to the dual canonical basis of the corresponding quantum unipotent subgroup. This talk is based on a joint work with Yoshiyuki Kimura. Affiliation:
