Title: Chiral differential operators on classical invariant rings
Time & Venue: 2026年5月15日（星期五）14：30-15：30 & 南楼N818
Abstract: We construct chiral analogues of differential operators acting on classical invariant rings as global sections of sheaves of chiral differential operators (CDO) associated with vector bundles on smooth open subvarieties of affine GIT quotients, using BRST reduction. As an application, we construct new infinite families of simple conformal quasi-lisse vertex algebras. This is a joint work in progress with Tomoyuki Arakawa and Xuanzhong Dai.
