Title : Introduction to Supercharge Q-cohomology and Fortuity Phenomenon
Abstract : I will introduce the supercharge Q-cohomology in holographic quantum field theories, and a classification of cohomology classes into monotone and fortuitous. I will discuss the holographic interpretation of the classification, focusing on N=4 SYM. Finally, I will discuss the behavior of the classical Q-cohomology under S-duality, and the potential quantum corrections to the cohomology.
Talk 2 (11:00-12:00)
Sunjin Choi
Title : Holography on ADE singularities
Abstract : I will talk about basic aspects of the AdS/CFT correspondence of four-dimensional N=4 U(N) super Yang-Mills theory when it is put on S3/\Gamma, where \Gamma is an arbitrary finite subgroup of SU(2). After giving a field-theoretical derivation that there is a huge vacuum degeneracy due to the choice of gauge holonomy, I will describe in detail a chain of string dualities, which maps this vacuum degeneracy to that of three-dimensional level-N Chern-Simons theory whose gauge group is determined by \Gamma. I will also briefly comment on how the S-duality and the one-form symmetry act in this duality.
