Tripled coincidence points for mixed comparable mappings in partially ordered cone metric spaces over Banach algebras

Let ( X, d ) be a complete partially ordered cone metric space, g : X → X and F : X × X × X → X be two mappings. In this paper, a new concept of F having the mixed comparable property with respect to g is introduced and some tripled coincidence point results of F and g are obtained if F has the mixed comparable property with respect to g and some other natural conditions are satisfied. Moreover, a support example of one of our results is given.
