Multiplication operators between discrete Hardy spaces on rooted trees

P. Muthukumar, P. Shankar

Muthukumar and Ponnusamy \cite{MP-Tp-spaces} studied the multiplication operators on $T_{p}$ spaces. In this article, we mainly consider multiplication operators between $\m…

Composition operators on Hardy spaces of the homogenous rooted trees

Perumal Muthukumar, Saminathan Ponnusamy

In \cite{CO-Tp-spaces}, the present authors initiated the study of composition operators on discrete analogue of generalized Hardy space $T_{p}$ defined on a homogeneous r…

Beurling type invariant subspaces of composition operators

Snehasish Bose, P. Muthukumar, Jaydeb Sarkar

Let $D$ be the open unit disk in $C$ , let $H^{2}$ denote the Hardy space on $D$ and let $φ : D \to D$ be a holomorphic self map of…
