New fixed point results for Proinov–Suzuki type contractions in metric spaces

We consider two new classes of contractions and obtain some new fixed point results in complete metric spaces. The mapping considered herein are not necessarily continuous on their domains. Many, well-known generalizations and extensions of the classical Banach contraction theorem have been extended and generalized. We present some illustrative examples to show the genuineness of our results. Finally, an application of our results to nonlinear integral equations is discussed.
