Remarks on equilibria for g-monotone maps on generalized convex spaces

Recently, Oettli and Schläger obtained existence results for a class of vectorial equilibrium problems involving g-monotone multimaps. In this paper, we obtain sharpened generalizations of their results.We are based on the KKM theorems for generalized convex spaces and fixed point theorems for the better admissible class of multimaps.  2002 Elsevier Science (USA).
