The maximal monotonicity of the subdifferentials of convex functions: Simons' problem

  • Dariusz Zagrodny
Article

Abstract

In the paper we deal with the problem when the graph of the subdifferential operator of a convex lower semicontinuous function has a common point with the product of two convex nonempty weak and weak* compact sets, i.e. when graph ∂ψ ∩ (Q × Q*) ≠ 0. The results obtained partially solve the problem posed by Simons as well as generalize the Rockafellar Maximal Monotonicity Theorem.
