Abstract

It is shown that if CC is a nonempty convex and weakly compact subset of a Banach space XX with M(X)>1M(X)>1 and T:CCT:C\rightarrow C satisfies condition (C)(C) or is continuous and satisfies condition (Cλ)(C_{\lambda}) for some λ(0,1)\lambda \in (0,1), then TT has a fixed point. In particular, our theorem holds for uniformly nonsquare Banach spaces. A similar statement is proved for nearly uniformly noncreasy spaces.
