Convexity of the Berezin range of operators on ${\mathcal{H}}_{\gamma }(\mathbb{D})$

Abstract

In this paper, we characterize the convexity of the Berezin range for finite-rank operators acting on the weighted Hardy space ${\mathcal{H}}_{\gamma }(\mathbb{D})$ over the unit disc $\mathbb{D}$. We provide a complete classification in terms of convexity for concrete operators. Additionally, we address dynamical properties of finite-rank operators on Hardy and Bergman spaces. Several illustrative examples are discussed to support our theoretical findings. Additionally, geometrical interpretations have also been employed.
