Finite rank intermediate Hankel operators

摘要

1. Introduction. Let 3) denote the open unit disc in the complex plane and let L2 (S#) be the usual Hilbert space of square integrable functions on Si. Here and throughout this paper all integrations are taken with respect to the usual two dimensional Lebesgue measure. The Bergman space A2 is defined to be the subspace of all analytic functions in L~2(?).
