During the last 20 years, ``localization'' has been one of the dominant themes in the area of equivariant differential geometry. Typical results are the Duister

This research monograph presents results in a rapidly developing area of great contemporary interest. Guillemin, Ginzburg, and Karshon show that the underlying

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

This monograph could be used for a graduate course on symplectic geometry as well as for independent study. The monograph starts with an introduction of symplec

This monograph, which grew out of a series of lectures delivered by Stephen Wiggins at the Fields Institute in early 1993, is concerned with the geometrical vie
