A quadruple fixed point theorem for contractive type condition by using ICS mapping and application to integral equation

Abstract

In this paper, we obtain a Quadruple fixed point theorem for ψ - φ contractive condition in partially ordered partial metric spaces by using ICS mapping. We are also given an example and an application to integral equation which supports our main theorem.
