Common fixed point theorems for c c -distance in ordered cone metric spaces ?
Recently, Cho etal. [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) 12541260] introduced the concept of the c c -distance in a cone metric space and established some fixed point theorems on c c -distance. The aim of this paper is to extend and generalize the main results of Cho etal.[20] and also show some examples to validate our main results.
