Weighted superposition operators on Fock spaces

Tesfa Mengestie

We characterize all pairs of entire functions $(u, ψ)$ for which the induced weighted superposition operator $S_{(u, ψ)}$ transforms one Fock space into another Fock space.Further an…

Surjective and closed range differentiation operator

Tesfa Mengestie

We identify Fock-type spaces $F_{(m, p)}$ on which the differentiation operator $D$ has closed range. We prove that $D$ has closed range only if it is surjective, and this…

Dynamics of the Volterra-type integral and differentiation operators on generalized Fock spaces

José Bonet, Tesfa Mengestie, Mafuz Worku

Various dynamical properties of the differentiation and Volterra-type integral operators on generalized Fock spaces are studied. We show that the differentiation operator is always…

Supercyclicity and resolvent condition for weighted composition operators

Tesfa Mengestie, Werkaferahu Seyoum

For pairs of holomorphic maps $(u, ψ)$ on the complex plane, we study some dynamical properties of the weighted composition operator $W_{(u, ψ)}$ on the Fock spaces. We prove that no…

Convex-cyclic weighted composition operators and their adjoints

Tesfa Mengestie

We characterize the convex-cyclic weighted composition operators $W_{(u, ψ)}$ and their adjoints on the Fock space in terms of the derivative powers of $ψ$ and the location of the…

Spectrums and uniform mean ergodicity of weighted composition operators on Fock spaces

Werkaferahu Seyoum, Tesfa Mengestie

For holomorphic pairs of symbols $(u, ψ)$ , we study various structures of the weighted composition operator $W_{(u, ψ)} f = u \cdot f (ψ)$ defined on the Fock spaces $F_{p}$ .…
