Surface operators in AN-theories of class S, and conformal field theory Teschner, Joerg
Description
The relations between class S theories and CFT get enriched further in the presence of surface operators. In the case of codimension 4 surface operator one expects relations to the conformal blocks of the W-algebra with extra degenerate fields inserted. The goal in my talk will be to describe simple aspects of the interplay between surface and line operators in gauge theory and CFT. The origin from the six-dimensional (2,0) theory suggests analogies (relations?) to the geometric Langlands correspondence.
