Common fixed point theorems for four mappings on cone metric type space

Abstract

In this paper we consider the so called a cone metric type space, which is a generalization of a cone metric space. We prove some common fixed point theorems for four mappings in those spaces. Obtained results extend and generalize well-known comparable results in the literature. All results are proved in the settings of a solid cone, without the assumption of continuity of mappings. © 2011 Aleksandar S. Cvetkovi et al.
