Marques Alves and B. F. Svaiter [J. Convex Analysis 15 (2008) 345348] that the subdifferential of a proper, convex lower semicontinuous function on a real Banach space is maximally monotone. We also show how the argument can be simplified in the reflexive case. [ Fulltextpdf (74 KB)] for subscribers only.
