Given a classical semisimple complex algebraic group G and a symmetric pair (G, K) of Hermitian type, we study the closures of the spherical nilpotent K-orbits in the isotropy representation of K. We show that all such orbit closures are normal and describe the K-module structure of their ring of regular functions.

Abstract
Given a classical semisimple complex algebraic group G and a symmetric pair (G, K) of Hermitian type, we study the closures of the spherical nilpotent K-orbits in the isotropy representation of K. We show that all such orbit closures are normal and describe the K-module structure of their ring of regular functions.File in questo prodotto:
