We introduce some new generalization of fixed point theorems in complete metric spaces endowed withw-distances viaR-functions. Our results extend many of known fixed point theorems such as Reich type contraction, Geraghty contraction, Meir-Keeler contraction, andZ-contraction. In addition, the result and corollaries show that our approach has a constructive attitude and many known and unknown results can be constructed in such way.
The aim of the current paper is introducing a generalization of Darbo's fixed point theorem based on SR−functions. In comparison with simulation function, SR−functions are able to cover the Meir-Keeler functions. Thus, the integral equations which are related to L−functions can be solved by our results. In the sequel, we find a solution for an integral equation to support our results.
