Informal Friday Seminar: Chan -- Isomorphisms on sale

Title: Isomorphisms on sale 

Speaker: Charlotte Chan, The University of Michigan 

Abstract: We learn from character theory that any representation is uniquely
characterized by its trace character, a conjugation-invariant function.  Experience
tells us that in general, character formulae for representations can be very
complicated.  This leads us to the following natural question: can we recognize
representations from a selective set of character values? I will discuss joint work with
Masao Oi where we study this question for several families of groups, including finite
groups of Lie type and p-adic groups.  

Details: The Informal Friday Seminar is a space where members of our research group can
explain interesting things to each other in a casual setting.  

The rules of the seminar are the following: 

Any question/additional explanation from the audience is allowed.  

Ego out the window.  

Examples, examples, examples.
