Abstract
In this paper, we investigate the concept of demicompactness and we establish
some new results in Fredholm theory connected with the existence of
selections of a given linear relation and we explore the possibility of
finding a selection demicompact for some linear relation demicompact.
Moreover, we give the relationship of the resolvent set between the linear
relation with its selection. Furthermore, we give an application to matrix
linear relation.
