 Let \(A\) be a finite abelian group. The author sets up an algebraic framework for studying \(A\)equivariant complexorientable cohomology theories in terms of a suitable kind of equivariant formal group. He computes the equivariant cohomology of many spaces in these terms, including projective bundles (and associated Gysin maps), Thom spaces, and infinite Grassmannians.
