K.P.R. Rao, G.N.V. Kishore, K.V. Siva Parvathi

In this paper, we obtain a Quadruple fixed point theorem for $\psi-\phi$ 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.
