Abstract

In this paper, we characterize the convexity of the Berezin range for finite-rank operators acting on the weighted Hardy space Hγ(D)\mathcal{H}_\gamma (\mathbb{D}) over the unit disc D\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.
