Geometry and Physics Seminar (GPS)

Time: Dec 30, 10:00-12:00Place: Teaching Building No.1, Room 102. TsinghuaTitle: Higher chiral algebras and free field realizationsSpeaker: Zhengping Gui (SIMIS and Fudan U.)Abstract: We use the Jouanolou model as a model for configuration spaces to construct higher-dimensional chiral algebras. In this model, chiral algebras can be studied as homotopy Lie algebras within a pseudotensor structu...

Geometric Representation Theory Seminar

Upcoming talks 2025/12/26 10:30-11:30 am, Shuangqing B627Yau Wing Li (University of Melbourne)Title: Endoscopy for metaplectic affine Hecke categoriesAbstract: The Hecke category is central in representation theory. A natural generalization considers sheaves on the enhanced affine flag variety with fixed monodromy along orbits of a centrally extended torus. In joint work with Gurbir Dhillon, Zh...
