What Is... Seminar

Allen Knutson
What is geometric representation theory?

Wednesday, October 28, 2020 - 5:30pm
Zoom

Partitions of n index both the Jordan canonical forms of
nilpotent nxn matrices, and the irreducible representations of $S_n$.
I'll explain how to construct the second from the first.
One upshot will be that the representations come with natural bases
(over the integers, even with some predictable signs).
I'll hint about how this generalizes to all representations of all
compact connected Lie (not finite) groups, and talk about some
open research directions.
