About the cohomological dimension of certain stratified varieties

Algebraic Geometry 2015-03-24 v2

Abstract

We determine an upper bound for the cohomological dimension of the complement of a closed subset in a projective variety which possesses an appropriate stratification. We apply the result to several particular cases, including the Bialynicki-Birula stratification; in this latter case, the bound is optimal.
