On the existence of ɛ-fixed points

Abstract

Abstract:In this paper we prove some approximate fixed point theorems which extend, in a broad sense, analogous results obtained by Brânzei, Morgan, Scalzo and Tijs in 2003. By assuming also the weak demiclosedness property we state two fixed point theorems. Moreover, we study the existence of ε-Nash equilibria. MSC:47H10, 47H04
