Convex-cyclic weighted composition operators and their adjoints
(Peer reviewed; Journal article, 2021)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 eigenvalues of the operators on the complex plane. ... -
Resolvent growth condition for the composition operator on the Fock space
(Peer reviewed; Journal article, 2020)For each analytic map ψ on the complex plane C, we study the Ritt’s resolvent growth condition for the composition operator Cψ:f→f∘ψ on the Fock space F2. We show that Cψ satisfies such a condition if and only if it is ...
