Progress in Mathematics

This is an extended second edition of "e;The Topology of Torus Actions on Symplectic Manifolds"e; published as Volume 93 in this series in 1991. The material and references have been updated. Symplectic manifolds and torus actions are investigated, with numerous examples of torus actions, for instance on some moduli spaces. Although the book is still centered on convexity results, it contains much more material, particularly lots of new examples and exercises.
