Affine pavings for affine Springer fibers for split elements in PGL(3)
arXiv:math/0309132
Abstract
This paper constructs pavings by affine spaces for the affine Springer fibers for PGL(3) obtained from regular compact elements in a split maximal torus. These pavings are constructed by intersecting the affine Springer fiber with a non-standard paving of the affine Grassmannian.
