Kernel-induced distance and its applications to Composition operators on Large Bergman spaces

Abstract

In this paper, we obtain a complete characterization for the compact difference of two composition operators acting on Bergman spaces with a rapidly decreasing weight $\omega =e^{-\eta }$, $\Delta \eta >0$. In addition, we provide simple inducing maps which support our main result. We also study the topological path connected component of the space of all bounded composition operators on $A^2(\omega )$ endowed with the Hilbert-Schmidt norm topology.
