Eric Swartz: Which finite groups are unit groups of finite rings?

Abstract: We say that a finite group $G$ is realizable if $G$ is the group of units of some finite ring $R$. It remains an open question precisely which groups are realizable, even if we restrict to commutative rings. We will discuss what is known about this problem, general approaches, and, time permitting, recent results (joint with Nicholas Werner) about the realizability of 2-groups.
