Description
Our main theorem is that the inclusion of a Birkhoff variety in the affine Grassmannian is a homotopy equivalence. We also construct analogues of tubular neighborhoods for Birkhoff and Schubert varieties. We include some observations on torus-equivariant cohomology.
This is a substantially revised version of an earlier submission. The main results are unchanged, but the proofs have been improved and simplified. We have also corrected an error regarding CW-structures on ind-varieties
