Abstract
We consider a see-saw pair consisting of a Hermitian symmetric pair and a compact symmetric pair , where and form a real reductive dual pair in a large symplectic group. In this setting, we get Capelli identities which explicitly represent certain -invariant elements in in terms of -invariant elements in . The corresponding -invariant elements are called Capelli elements.
We also give a decomposition of the intersection of -harmonics and -harmonics as a module of , and construct a basis for the highest weight vectors. This intersection is in the kernel of our Capelli elements.
