报告摘要：
The works of Brylinski-Kashiwara and Berenstein-Gelfand-Gelfand illustrated that we could understand representation theory of Lie algebras via algebraic geometry of flag
varieties. This phenomena turned out to include many other situations, including representation theory of quivers: we can associate to a given representation-theoretic data an algebraic symplectic variety, whose "category O" recovers the desired representation-theoretic data. Recent understanding of the geometric nature of such varieties expects that category Os should actually be symplectic invariants. In this talk, I'll explain one case where this expectation is verified. This is based on the recent joint work with Sukjoo Lee, Yin Li and Cheuk Yu Mak.
