Common fixed point theorems for c-distance in ordered cone metric spaces
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 c-distance in a cone metric space and established some fixed point theorems on c-distance. The aim of this paper is to extend and generalize the main results of Cho et al. [20] and also show some examples to validate our main results. (C) 2011 Elsevier Ltd. All rights reserved.
