Generalized Weakly Demicompact and S-Demicompact Linear Relations and Their Spectral Properties
We extend the concept of generalized weakly demicompact and relatively weakly demicompact operators on linear relations and present some outstanding results. Moreover, we address the theory of Fredholm and upper semi-Fredholm relations and make an attempt to establish connections with these operators.
