Shadowing for weighted composition operators on spaces of continuous functions

Abstract

In this work, we characterize the shadowing property for weighted shifts on a general class of Banach sequence spaces, extending a theorem proved by Bernardes et al. in ETDS (2020). We then apply this result to characterize this property for weighted composition operators acting on a class of Banach spaces of continuous functions. As an application, we present a characterization of shadowing for bilateral weighted translations on the spaces $C_b(\mathbb{R})$ and $C_0(\mathbb{R})$. In a more general setting, we provide sufficient conditions for weighted composition operators to have the shadowing property. These conditions allow us to obtain complete characterizations of this property for multiplication operators on the Hardy spaces $H^p(\mathbb{D})$, $p\in [1,\infty ]$, as well as on spaces of the form $H^{\infty }(\hat{I}\text{c◯})$ or $C_b(\hat{I}˜)$.
