Query: Regular functions on spherical nilpotent orbits in complex symmetric
  pairs: classical Hermitian cases   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.
