Multiplication operators on $S^2(\mathbb D)$

Abstract

In this paper, we study the multiplication operators on S2S^2, the space of analytic functions on the open unit disk D\mathbb D whose first derivative is in H2H^2. Specifically, we characterize the bounded and the compact multiplication operators, establish estimates on the operator norm, and determine the spectrum. Finally, we prove that the isometric multiplication operators are precisely those induced by a constant function of modulus one.
