Reflexivity on Banach Spaces of Analytic Functions

Let X be a Banach space of functions analytic on a plane domain ­ such that for every ¸ in ­ the functional of evaluation at ¸ is bounded. Assume further that X contains the constants and admits multiplication by the independent variable z, Mz, as a bounded operator. We give su±cient conditions for Mz to be reflexive
