Recently, C. Zalinescu ["A new convexity property for monotone operators", Journal of Convex Analysis 13 (2006) 883--887] posed a question about the characterization of the intrinsic core of the Minkowski sum of two graphs associated with two maximal monotone operators. In this note we give an affirmative answer.
Keywords: Convex function, convex set, Fenchel conjugate, Fitzpatrick function, intrinsic core, maximal monotone operator, monotone operator, multifunction, relative algebraic interior, representative, set-valued operator.
