Abstract:In this paper, we investigate the notion of analytic core and quasi-nilpotent
part of a linear relation. Furthermore, we are interested in studying the
set of Generalized Kato linear relations to give some of their properties in
connection with the analytic core and the quasi-nilpotent part. We finish by
giving a perturbation result for this set of linear relations.
“…Most properties of these latter subspaces are also gathered. The stated results generalize the concepts of quasinilpotent part and the analytic core recently introduced in [12] to the setting of closed not necessary bounded linear relations. Section 3 begins by a generalization to the case of closed linear relations of [9, Theorem 3.1] stated above.…”

“…Now, let's further extend the concepts of quasinilpotent part and the analytic core developed in [11,12] to the case of closed not necessary bounded linear relations. Definition 2.1.…”

We investigate in this paper the isolated points of the approximate point spectrum of a closed linear relation acting on a complex Banach space by using the concepts of quasinilpotent part and the analytic core of a linear relation.
