Query: Distinguishing the Chambers of the Moment Polytope   Let M be a compact manifold with a Hamiltonian T action and moment map Phi.
The restriction map in equivariant cohomology from M to a level set Phi^{-1}(p)
is a surjection, and we denote the kernel by I_p. When T has isolated fixed
points, we show that I_p distinguishes the chambers of the moment polytope for
M. In particular, counting the number of distinct ideals I_p as p varies over
different chambers is equivalent to counting the number of chambers.
