Abstract
In this paper we give a brief survey of some recent generalizations of the Fan-KKM theorem. We introduce a new convex structure on a nonempty set M which contains all different concepts of convexity. Some approximate fixed point theorems will be established for the multivalued mapping with S-KKM property on the [Phi] spaces. We also obtain a generalized Fan matching theorem, a generalized Fan-Browder type theorem, and a new version of Sadovskii's fixed point theorem.
