We establish b-coupled coincidence and b-common coupled fixed point theorems in such spaces. The presented theorems generalize and extend several well-known comparable results in the literature in particular the recent results of Abbas et al. Appl. Math. Comput. 217 195-202 2010 . Some examples are given to illustrate our obtained results. An application to the study of existence of solutions for a system of non-linear integral equations is also considered. 2010 Mathematics Subject Classifications 54H25 47H10. Keywords -compatible mappings b-coupled coincidence point b-common coupled fixed point cone metric space integral equation 1 Introduction Ordered normed spaces and cones have applications in applied mathematics for instance in using Newton s approximation method 1-4 and in optimization theory 5 . K-metric and K-normed spaces were introduced in the mid-20th century 2 see also 3 4 6 by using an ordered Banach space instead of the set of real numbers as the codomain for a metric. Huang and Zhang 7 re-introduced such spaces under the name of cone metric spaces and went further defining convergent and Cauchy sequences in the terms of interior points of the underlying cone. Afterwards many papers about fixed point .
