Complex symmetric operators have attracted significant attention in recent years owing to their intriguing spectral properties and the elegance of their underlying mathematical structures. At their ...

Composition operators, which act on spaces of analytic functions by composing with a fixed analytic self-map, are a central topic in modern functional analysis. In particular, their study on Bergman ...

We prove that any composition operator with maximal norm on one of the weighted Bergman spaces $A_{\alpha}^2$ (in particular, on the space $A^{2} = A_{0}^2$) is ...

We study the composition operators on an algebra of Dirichlet series, the analogue of the Wiener algebra of absolutely convergent Taylor series, which we call the Wiener-Dirichlet algebra. The central ...
