An extension of the paper “Cone metric spaces and fixed point theorems of contractive mappings”
About this article
Abstract
Huang and Zhang [1] established the results of xed point theorems using contractive method in cone metric space. Later on, Rezapour and Hamlbarani[2] generalize the results [1] with non-normal cones and omitted the assumptionof normality. In the present paper we improve these results.References
