Moment Maps and Combinatorial Invariants of Hamiltonian Tn-spaces by Victor Guillemin.
The action of a compact Lie group, G, on a compact sympletic manifold gives rise to some remarkable combinatorial invariants. The simplest and most interesting of these is the moment polytope, a convex polyhedron which sits inside the dual of the Lie algebra of G. One of the main goals of this monog...
