Common fixed point theorems for -distance in ordered cone metric spaces

Abstract: Recently, Cho et al. [Y.J. Cho, R. Saadati, S.H. Wang, Common fixed point theorems on generalized distance in ordered cone metric spaces, Comput. Math. Appl. 61 (2011) 1254–1260] introduced the concept of the -distance in a cone metric space and established some fixed point theorems on -distance. The aim of this paper is to extend and generalize the main results of Cho et al.  and also show some examples to validate our main results. [Copyright &y& Elsevier]
