Multiplicity on a Richardson variety in a cominuscule G/P

Algebraic Geometry 2013-05-21 v2

Abstract

We show that in a cominuscule partial flag variety G/P, the multiplicity of an arbitrary point on a Richardson variety X_w^v = X_w \cap X^v is the product of its multiplicities on the Schubert varieties X_w and X^v.
