Abstract: Fusion categories were intensively studied in the last twenty years in connections with many fields of mathematics such as representation theory, quantum groups, algebraic topology, operator algebras, combinatorics and others. Recently, Kenichi Shimizu introduced a notion of a character associated with each object of a pivotal fusion category. In this talk we will discuss some aspects of the character theory of finite groups that can be extended to pivotal fusion categories. Some of their consequences to the structure of the categories and their Grothendieck groups will also be presented.
