A GENERALIZATION OF BANACH CONTRACTION PRINCIPLE IN ORDERED CONE METRIC SPACES

Abstract

In this paper we prove fixed point theorems for ordered ´ Ciric-Presict ype contraction in cone metric spaces without assuming the normality of cone. These results generalize and extend the Banach contraction principle and several known results in ordered cone metric spaces. Some examples are presented to illustrate the cases when new results can be applied while old one can not.
