Formal GAGA for good moduli spaces

Algebraic Geometry 2015-07-02 v2

Abstract

We prove formal GAGA for good moduli space morphisms under an assumption of "enough vector bundles" (which holds for instance for quotient stacks). This supports the philosophy that though they are non-separated, good moduli space morphisms largely behave like proper morphisms.
