Distinguishing the Chambers of the Moment Polytope
Distinguishing the Chambers of the Moment Polytope
Let M be a compact manifold with a Hamiltonian T action and moment map Φ.The restriction map in rational equivariant cohomology from M to a level set Φ -1 (p) is a surjection, and we denote the kernel by I p .When T has isolated fixed points, we show that …
