On the Restrictions of Weakly Demicompact Operators and Generalized Fredholm Theory

The purpose of this paper is to explore the weak demicompactness of the operator $T_n$, which is the restriction of a linear operator $T$ to its range $\mathcal{R}(T^n)$, $T_n$ are considered as linear operators from $\mathcal{R}(T^n)$ to itself, $n\in\mathbb{N}$. As well, we present several results...
