Noetherianity in representation theory


Speaker: Steven Sam, University of Wisconsin
Location: 1147 MSB

Representation stability is an exciting new area that combines
ideas from commutative algebra and representation theory. The meta-idea
is to combine a sequence of objects together using some newly defined
algebraic structure, and then to translate abstract properties about
this structure to concrete properties about the original object of
study. Finite generation is a particularly important property, which
translates to the existence of bounds on algebraic invariants, or some
predictable behavior. I'll discuss some examples coming from
combinatorial representation theory (Kronecker coefficients) and
topology (configuration spaces).

Refreshments will be served before the talk!
