In mathematics, equivariant cohomology (or Borel cohomology) is a cohomology theory from algebraic topology which applies to topological spaces with a group action. It can be viewed as a common generalization of group cohomology and an ordinary cohomology theory. Specifically, the equivariant … See more It is also possible to define the equivariant cohomology $${\displaystyle H_{G}^{*}(X;A)}$$ of $${\displaystyle X}$$ with coefficients in a $${\displaystyle G}$$-module A; these are abelian groups. This construction is the … See more Let E be an equivariant vector bundle on a G-manifold M. It gives rise to a vector bundle $${\displaystyle {\widetilde {E}}}$$ on the homotopy quotient $${\displaystyle EG\times _{G}M}$$ so that it pulls-back to the bundle $${\displaystyle {\widetilde {E}}=EG\times E}$$ See more • Equivariant differential form • Kirwan map • Localization formula for equivariant cohomology • GKM variety • Bredon cohomology See more The homotopy quotient, also called homotopy orbit space or Borel construction, is a “homotopically correct” version of the See more The following example is Proposition 1 of [1].
