Download or read book Moment Maps and Combinatorial Invariants of Hamiltonian Tn̳-spaces written by Victor Guillemin and published by Birkhauser. This book was released on 1994 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 polytopes, a convex polyhedron which sits inside the dual of the Lie algebra of G. One of the main goals of this monograph is to describe what kinds of geometric information are encoded in this polytope. This book is addressed to researchers and can be used as a semester text.
