Abstract

Complementing earlier results on dynamics of unilateral weighted shifts, we obtain a sufficient (but not necessary, with supporting examples) condition for hypercyclicity, mixing and chaos for MzM_z^*, the adjoint of MzM_z, on vector-valued analytic reproducing kernel Hilbert spaces H\mathcal{H} in terms of the derivatives of kernel functions on the open unit disc D\mathbb{D} in C\mathbb{C}. Here MzM_z denotes the multiplication operator by the coordinate function zz, that is (Mzf)(w)=wf(w), (M_z f) (w) = w f(w), for all fHf \in \mathcal{H} and wDw \in \mathbb{D}. We analyze the special case of quasi-scalar reproducing kernel Hilbert spaces. We also present a complete characterization of hypercyclicity of MzM_z^* on tridiagonal reproducing kernel Hilbert spaces and some special classes of vector-valued analytic reproducing kernel Hilbert spaces.
