Abstract

摘要

The Coulomb branch indices of Argyres-Douglas theories on L(k,1)×S1 are recently identified with matrix elements of modular transforms of certain 2d vertex operator algebras in a particular limit. In this talk I will present a one parameter generalization of the modular transformation matrices of (2N+3,2) minimal models in order to compute the full Coulomb branch index of (A1,A2N) Argyres-Douglas theories on the same space. Morever, M-theory construction of these theories suggests direct connection to the refined Chern-Simons theory. The connection is made precise by showing how the modular transformation matrices of refined Chern-Simons theory are related to the proposed generalized ones for minimal models and the identification of Coulomb branch indices with the partition function of the refined Chern-Simons theory.
