**Title: ***Using super-geometry to understand equivariant prime ideals*

**Abstract: **Let A be a commutative algebra equipped with an action of a group G. The so-called G-primes of A are the equivariant analogs of prime ideals, and of central importance in equivariant commutative algebra. We will discuss recent work (joint w/ Andrew Snowden) about how one can use geometry, specifically super-geometry, to understand equivariant prime ideals. Our main example will be a specific isomeric algebra whose spectrum is, more or less, the space of infinite isomeric matrices (more commonly known as "queer matrices").
