题目：BPS invariants for Seifert manifolds from Chern-Simons matrix model 

报告人：Prof. Hee-Joong Chung（清华大学）

Abstract：

In this talk, I first provide an introduction to the homological block of the Witten-Reshtikhin-Turaev (WRT) invariants for closed 3-manifolds. The homological block is a q-series with integer powers and integer coefficients, which are necessary properties for the categorification. In physics, such q-series can be interpreted as certain BPS invariants. I will also discuss the WRT invariants from the Chern-Simons matrix model. Then, I will talk about the calculation of homological blocks for Seifert manifolds with gauge group G=SU(N).
