Moduli of vector bundles on curve and semiorthogonal decomposition

Time：Wed.,14:00-15:00, June 14, 2023

Venue：Lecture Hall, 3rd floor Jinchun Yuan West Building

Organizer：李思

Speaker：Kai Xu Harvard University

Abstract

We will construct semiorthogonal decompositions of moduli of vector bundles on a curve C into the symmetric powers of C. As essential ingredients in the proof, we will develop Borel-Weil-Bott theory for loop groups on twisted moduli spaces and derived Schur-Weyl duality for current groups. We will also discuss the relation with supersymmetric gauge theory.

Line bundles on moduli stack of parahoric bundles
Line bundles on moduli spaces/stacks of G-bundles were studied intensively in 90’s by many mathematicians including Beauville, Laszlo, Sorger, Faltings, Kumar, Narasimhan, Teleman, etc. The main problems are the Verlinde formula for the dimension of global sections of these line bundles, and the determination of the Picard groups of the moduli spaces/stack of G-bundles.In this talk, I will dis...
