Computation of weighted Bergman inner products on bounded symmetric domains and restriction to subgroups (Japanese)
[ Abstract ]
Let $D¥subset M(r,¥mathbb{C})$ be the bounded symmetric domain, and we consider the weighted Bergman space $¥mathcal{H}_¥lambda(D)$ on $D$. Then $SU(r,r)$ acts unitarily on $¥mathcal{H}_¥lambda(D)$.
In this seminar, we compute explicitly the inner products for some polynomials on $¥operatorname{Alt}(r,¥mathbb{C})$, $¥operatorname{Sym}(r,¥mathbb{C})¥subset M(r,¥mathbb{C})$, and prove that the inner products are given by multivariate hypergeometric polynomials when the polynomials are some powers of the determinants or the Pfaffians.
As an application, we present the results on the construction of symmetry breaking operators from $SU(r,r)$ to $Sp(r,¥mathbb{R})$ or $SO^*(2r)$.
