The Quantum McKay Correspondence: Classifying "Finite Subgroups" of a Quantum Group with Graphs Öffentlichkeit

Abstract

The McKay Correspondence classifies finite subgroups of the rotation group of 3-space via graphs. In this paper we explore a quantum version of this correspondence. Specifically, we will cover the needed background on category theory, vertex operator algebras, and quantum groups to explain a powerful technique used by Kirillov and Ostrik to develop a quantum analog to the McKay correspondence.
