Geometric Representation Theory Seminar

Upcoming talks 2025/11/28 10:30-11:30 am, Shuangqing B627Xuanzhong Dai 戴烜中 (RIMS)A uniform geometric construction of chiral differential operatorsIn this talk, we present a uniform geometric framework that connects the representation theory of vertex algebras with symplectic geometry and invariant theory. We construct chiral analogues of differential operators acting on classical invariant r...
