Fixed point theorems in r-normed and locally r-convex spaces and applications

Abstract

. In this paper we prove some new fixed point theorems in r -normed and locally r -convex spaces. Our conclusions generalize many well-known results and provide a partial affirmative answer to Schauder’s conjecture. Based on the obtained results, we prove the analogue of a Von Neumann’s theorem in locally r -convex spaces. In addition, an application to game theory is presented.
