Fixed-Copy Exponent Sets and Strict Singularity of Composition Operators Between Hardy Spaces
Yecheng Shi, Songxiao Li
For a bounded operator \(T\) between Banach spaces, we introduce the \emph{fixed-copy exponent sets} \[ \begin{aligned} \operatorname{Fix}_{\ell}(T) &:= \{r\ge1:T\text{ fixes a cop…

Generalized weighted composition operators on weighted Hardy spaces
Lian Hu, Songxiao Li, Rong Yang
In this paper, we investigate the complex symmetric structure of generalized weighted composition operators on the weighted Hardy space . We obtain explicit con…
