SOME COUPLED FIXED POINT THEOREMS FOR MAPPINGS SATISFYING RATIONAL TYPE CONTRACTIVE CONDITIONS IN PARTIALLY ORDERED METRIC SPACES
In this paper, some coupled fixed point theorems in partially ordered metric spaces are obtained by using rational type contractive conditions without imposing continuity requirement on the mappings. Some results on sequences of coupled fixed point are also discussed. Our results improve, extend and generalize several known results in the literature.
