概要 We consider a see-saw pair consisting of a Hermitian symmetric pair $(G_R, K_R)$ and a compact symmetric pair $(M_R, H_R)$. In this setting, we get Capelli identities which explicitly represent certain $K_C$-invariant elements in $U(\lieg_C)$ in terms of $H_C$-invariant elements in $U(\liem_C)$. We also give a decomposition of the intersection of $\OO_{2n}$-harmonics and $\Sp_{2n}$-harmonics as a module of $\GL_n = \OO_{2n} \cap \Sp_{2n}$.
