Title:
Push-forwards in equivariant cohomology and iterated residues at infinity
Abstract:
Localization theorems for equivariant cohomology of varieties
with torus action provide tools to express cohomological invariants
(for example integrals) only in terms of the fixed points of the action.
After giving a brief introduction to the equivariant cohomology theory, I will
show how to express an integral (over a homogeneous space of a classical
Lie group) as an iterated resiude at infinity of a certain function.
