Good moduli spaces for Artin stacks
Abstract: I will develop an intrinsic theory for associating schemes
or algebraic
spaces with nice geometric properties to arbitrary Artin stacks. This
theory offers a stack-theoretic approach to geometric invariant theory.
I will define the notion of a good moduli space which simultaneously
generalizes the existing notions of good GIT quotients and tame stacks.
I will also explore the local structure of Artin stacks and in
particular address whether Artin stacks are locally quotient stacks.
