Skew-symmetric and essentially unitary operators via Berezin symbols
Open Mathematics, 2020 We characterize skew-symmetric operators on a reproducing kernel Hilbert space in terms of their Berezin symbols. The solution of some operator equations with skew-symmetric operators is studied in terms of Berezin symbols.

Universal Sequences of Composition Operators
The Journal of Geometric Analysis, 2023 Let $G$ and $Ω$ be two planar domains. We give necessary and sufficient conditions on a sequence $(ϕ_n)$ of eventually injective holomorphic mappings from $G$ to $Ω$ for the existence of a function $f\in H(Ω)$ whose orbit under the composition by $(ϕ_n)$ is dense in $H(G)$. This extends a result of the same nature obtained by Grosse-Erdmann and Mortini

Differentiability Properties of an Abstract Autonomous Composition Operator
, 2000 We define an `abstract' composition operator of elements of a suitable Banach space, with the elements of a commutative Banach algebra with unity, and produce theorems of $r$-th order differentiability for such operator.

Composition-Differentiation Operator on the Bergman Space
Pan-American Journal of Mathematics, 2023 We investigate the properties of composition-differentiation operator Dψ on the Bergman space of the unit disk L2a(D). Specifically, we characterize the properties of the reproducing kernel for the derivatives of the Bergman space functions. Moreover, we
