Description: |
Supercharacter theories are generalizations of the usual character theory of a group. In this talk, we present the basics of supercharacter theory, emphasizing the supercharacter theory of the unitriangular groups and its combinatorial interpretations. In the second part of the talk, we construct graded graphs using restriction and superinduction of supercharacters and use them to determine the extreme supercharacters of the infinite unitriangular group.
