Deligne–Mumford stacks (via extensions)

E2218304 UNEXPLORED

Deligne–Mumford stacks (via extensions) are a generalization of algebraic varieties and schemes that incorporate mild stacky or orbifold-like structures, allowing intersection-theoretic tools such as Chow groups to be extended to more singular and moduli-type geometric objects.
