Title: 4D/2D duality and representation theory
Date: Thu, Sep 26, 2019, 15:30 - 17:00
Place: Seminar Room A
Abstract: The 4D/2D duality discovered by Beem et. al associates a vertex operator algebra (VOA) to any 4D N=2 SCFT.
The corresponding VOA not only gives the Schur index of the 4D theory as its character but is also expected to recover the Higgs branch as its associated variety. In this talk I will discuss the recent development of the representation theory of VOAs in view of the 4D/2D duality.
