Coupled fixed point on ordered cone metric spaces with application in integral equations

Our theorems are on ordered cone metric spaces which are not necessarily normal. In the end, we describe the application of the main results in the integral equation.Although Du in [W‎. ‎S‎. ‎Du‎, ‎A note on cone metric fixed point theory and its equivalence‎, ‎Nonlinear Analysis‎, ‎72(2010) 2259-2261.]‎, ‎showed that the fixed point results in the setting of cone metric spaces in which linear contractive conditions appear‎, ‎can be reduced to their respective results in the metric setting‎, ‎but it has been shown in the papers [W‎. ‎S‎. ‎Du, New cone fixed point theorems for nonlinear multivalued maps with their applications‎, ‎Applied Mathematic Letters,‎24(2011) 172-178.] and [S‎. ‎Jankovic‎, ‎Z‎. ‎Kadelburg‎, ‎S‎. ‎Radenovic‎, ‎On cone metric spaces‎: ‎A survey‎, ‎Nonlinear Analysis‎, ‎74(2011) 2591-2601‎.] ‎when‎, cone metric spaces are non-normal‎, the results may not hold‎.The results from our paper belong to this category‎.
