Products of differentiation operator and composition operator on H([[PI].
A typical problem is to provide function theoretic characterizations when [phi] induces a bounded or compact products of differentiation operator and composition operator between two given spaces of analytic functions.
2], in Section 2 we calculate the exact value of Hilbert-Schmidt norms of products of composition and differentiation operators [C.
