Nearly invariant subspaces in the real Hardy space
Arshad Khan, Sneh Lata, Dinesh Singh
The objective of this article is to study nearly invariant subspaces of the backward shift operator on the real Hardy space. We also investigate nearly invariant subspaces with fin…

Perturbations of Toeplitz operators on vector-valued Hardy spaces
Arshad Khan, Sneh Lata, Dinesh Singh
In this article, we completely classify invariant subspaces of finite-rank perturbations of a class of Toeplitz operators on vector-valued Hardy spaces. As a consequence, in the ve…

A several variables Kowalski-S\lodkowski theorem for topological spaces
Jaikishan, Sneh Lata, Dinesh Singh
In this paper, we provide a version of the classical result of Kowalski and Słodkowski that generalizes the famous Gleason-Kahane-elazko (GKZ) theorem by characterizin…
