Kirwan map
text:
In differential geometry, the Kirwan map, introduced by British mathematician Frances Kirwan, is the homomorphism where M is a Hamiltonian G-space; i.e., a symplectic manifold acted by a Lie group G with a moment map μ : M → g ∗ . H G ∗ is the equivariant cohomology ring of M ; i.e.. the cohomology ring of the homotopy quotient E G × G M of M by G . M / / p G = μ − 1 / G is the symplectic quotient of M by G at a regular central value p ∈ Z of μ . It is defined as the map of equivariant cohomolog
