equivariant mapIn mathematics, an equivariant map is a function between two sets that commutes with the action of a group. Specifically, let G be a group and let X and Y be two associated G-set

equivariant cohomologyIn mathematics, equivariant cohomology is a theory from algebraic topology which applies to spaces with a group actio It can be viewed as a common generalization of group cohomology and an ordinary cohomology theory.
