By Antun Milas
Appears in collection : Vertex Algebras and Representation Theory / Algèbres vertex et théorie des représentations
I'll discuss properties of character formulas of vertex (super)algebras in connection to: (a) 4d N=2 Argyres-Douglas theories, (b) class S theories, and (c) cohomological Hall algebras of symmetric quivers.
