WebIn general, the Chow group is an algebraic version of a homology theory. That is, the objects are formal linear combinations of submanifolds modulo relations.

Given an algebraic group acting on a scheme or stack, we give a sufficient criterion for its localized equivariant Borel-Moore homology to be concentrated in a given closed substack. We deduce this from a new kind of stacky concentration theorem.
