摘要：
We use the notion of radial differential operator of order t > 0 to introduce the weighted composition-differentiation operator E-psi, phi(t)(f) = psi <middle dot> (R-t f) o phi on the Hardy and Bergman spaces of the unit ball and the polydisk in C-n. We obtain necessary and sufficient conditions on the functions phi and psi to ensure that the operator E(psi,phi)(t)is Hilbert-Schmidt.
