We study the relationship between polynomial approximations in the Bergman space of certain simply connected domains in the complex plane and composition operators on the Dirichlet space of the unit disk. In particular, we characterize when a composi

In this paper, we study the so-called Hankel measures on the open unit disk. We obtain several new characterizations for such measures and answer a question raised by J. Xiao in 2000.

For entire functions f and g we study the problem of when the Hankel product H f ‾ ⁎ H g ‾ is bounded or compact on the Fock space F α 2 . This is a companion to Sarason's Toeplitz product problem which was completely solved for the Fock space

We introduce and study a class of Hausdorff-Berezin operators on the unit disc based on Haar measure (that is, the Mobius invariant area measure). We discuss certain algebraic properties of these operators and obtain boundedness conditions for them.

We obtain atomic decomposition for weighted Fock spaces Fφp whose weights φ satisfy a certain version of the doubling condition. We also characterize the dual space of these Fock spaces for any 0
