The sum theorem for maximal monotone operators in reflexive Banach spaces revisited
M. D. Voisei · Studia Universitatis Babes-Bolyai Matematica · 2021
The goal of this note is to present a new shorter proof for the maximal monotonicity of the Minkowski sum of two maximal monotone multi-valued operators defined in a reflexive Banach space under the classical interiority condition involving their domains.
