"T-equivariant cohomology of cell complexes and the case of infinite
Grassmannians"
Abstract:
We describe how to exted the techniques of Goresky, Kottwitz and
MacPherson to the (possibly infinite dimensional) setting of equivariant
CW complexes with only even dimensional cells. We show how to compute
equivariant cohomology of these spaces in a purely combinatorial way.
These results give insight to many (symplectic!) examples, including
certain coadjoint orbits of the loop group $LG$. This is joint work with
M.\ Harada and A.\ Henriques.
