Abstract
Let 𝒳 be reflexive Banach space of functions analytic plane domain
Ω such that for every λ in Ω the functional of evaluation at λ is bounded. Assume further that
𝒳 contains the constants and Mz multiplication by the independent variable z, is bounded
operator on 𝒳. We give sufficient conditions for Mz to be reflexive. In particular, we prove that
the operators Mz on EP(Ω) and certain HaP(β) reflexive. We also prove that the algebra
of multiplication operators on Bergman spaces is reflexive, giving simpler proof of result of
Eschmeier.
