Add to ORKGAbstract. General structure results about Deligne–Mumford stacks are sum-marized, applicable to stacks of finite type over a field. When the base field has characteristic 0, a class of “(quasi-)projective ” Deligne–Mumford stacks is iden-tified, defined to be those that embed as a (locally) closed substack of a smooth proper Deligne–Mumford stack having projective coarse moduli space. These conditions are shown to be equivalent to some well-studied hypotheses. 1
