5:10PM: Invariant Theory of Some Finite Groups

The invariant theory of finite reflection groups appears often in Lie theory, and it is surprisingly very simple to describe in characteristic zero. In fact, this simplicity characterizes these groups among all finite groups. After surveying the classical story for reflection groups, we will look at what is and isn't known more generally.
