    Relationship between T and u in ∇T for other types of summability
    (Mohamed Boudiaf University of Msila, Faculty of Mathematics and Computer Sciences, Department of Mathematics, 2024-06) Ouadah, Chourouk; Mezrag, Lahcen: Supervisor; Talleb, Abdelhamid: Co-Supervisor.
    In this memory, we introduce and study the notions of summability in the sublinear case. We prove some characterizations in terms of a domination theorem and some properties of this notions.we are interested in studying the relationship between T and its subdifferential ∇T (the set of all bounded linear operators u : X −→ Y such that u(x) ≤ T(x) for all x in X) ; concerning certain notions of Lipschitz summability.
