Continuity and Holomorphicity of Symbols of Weighted Composition Operators

Abstract

The main problem considered in this article is the following: if $\mathbf{F}$, $\mathbf{E}$ are normed spaces of continuous functions over topological spaces $X$ and $Y$ respectively, and $\omega :Y\to \mathbb{C}$ and $\Phi :Y\to X$ are such that the weighted composition operator $W_{\Phi ,\omega }$ is continuous, when can we guarantee that both $\Phi$ and $\omega$ are continuous? An analogous problem is also considered in the context of spaces of holomorphic functions over (connected) complex manifolds. Additionally, we consider the most basic properties of the weighted composition operators, which only have been proven before for more concrete function spaces.
