# Coarse Moduli space of proper Deligne-Mumford stacks

Let F be a finite type proper Deligne-Mumford Stack over a perfect field. Is it true that the coarse moduli space of F is proper?

-
The map from the stack to the space is a proper homeomorphism - so yes. Brian Conrad has a "modern" proof of Keel and Mori's theorem on the existence of coarse moduli spaces which you may find interesting (and can find on his webpage). –  mdeland Apr 8 '11 at 12:31
