Abstract
The main purpose of this article is to give a relationship between Fredholm multivalued linear operators and the demicompact linear relation; we provide some sufficient conditions on the inputs of a closable block multivalued linear operator matrix to ensure the generalized demicompactness of its closure. Our results generalize many known ones in the literature.
