Title: Prime ideals in twisted commutative algebras
Abstract: In representation stability, we are usually in a setting where a large
group G is acting on a large ring R. In this case, we will define the "correct"
notion of a prime ideal. Afterwards, we will discuss a key result of Snowden
(arXiv:2002.01152) which provides a link between these newlydefined
prime ideals and ordinary prime ideals when R is a twisted commutative
algebra (and G = GL).
