Hyponormality on a weighted Bergman space of an annulus with a general harmonic symbol

open access: yesOpen Mathematics
In this work we consider the hyponormality of Toeplitz operators on the Bergman space of the annulus with a logarithmic weight. We give necessary conditions when the symbol is of the form φ+ψ̄ $\varphi +\bar{\psi }$ where both φ and ψ are analytic on ...

Adjoints of Generalized Composition Operators with Linear Fractional Symbol

open access: yesExtracta Mathematicae, 2016
Given a positive integer n and φ : U → U, an analytic self-map of the open unit disc in the complex plane, the generalized composition operator Cφ(n) is defined by Cφ(n)f = f (n) ◦ φ for f belonging to some Hilbert space of analytic functions on U.

Description of Bloch spaces, weighted Bergman spaces and invariant subspaces, and related questions

open access: yesKuwait Journal of Science, 2016
Let D be the unit disc of complex plane C, and H=Hol(D) the class of functions analytic in D. Recall that an f∈Hol(D) is said to belong to the Bloch space B=B(D) if ‖f‖_{B}:=sup_{z∈D}(1-|z|²)|f′(z)|
