Homology of the zero-set of a nilpotent vector field on a flag manifold
Homology of the zero-set of a nilpotent vector field on a flag manifold
0.1. Let X be a linear transformation of a finite-dimensional vector space V. The configuration of flags in V which are fixed by X has rather remarkable properties when X is unipotent. Though this case is especially interesting, the proper generality in which to study such configurations is in the …
