Generic singularities of certain Schubert varieties

Abstract

Let G be a connected semisimple algebraic group, B a Borel subgroup, T a maximal torus in B with Weyl group W , and Q a subgroup containing B. For w ∈ W , let XwQ denote the Schubert variety BwQ/Q. For y ∈ W such that XyQ ⊆ XwQ, one knows that ByQ/Q admits a T -stable transversal in XwQ, which we denote by NyQ,wQ. We prove that, under certain hypotheses… (More)
