Nuclear Weighted composition operators between different $L^{p}$ -spaces

S. Al Ghafri, Y. Estaremi, S. Shamsigamchi

We provide complete characterisations of nuclear weighted composition operators between two distinct $L^{p} (I^¼)$ -spaces, where $1 \leq p < \infty$ . As a consequence, when the underlying…

Weighted conditional expectation operators and nuclearity

M. S. Al Ghafri, S. Shamsigamchi, Y. Estaremi

We provide a characterisations of nuclear weighted conditional expectation operators on $L^{p} (I^¼)$ -spaces, for $1 \leq p < \infty$ . As a consequence, when the underlying measure space…

On a class of m-Isometric and Quasi-m-isometric operators

Y. Estaremi, M. S. Al Ghafri, S. Shamsigamchi

In this paper we characterize $m$ -isometric and quasi- $m$ -isometric weighted conditional type (WCT) operators on the Hilbert space $L^{2} (I^¼)$ . Also, we prove that the subclasses of…
