A Generalization of the MeirKeeler Condensing Operators and its Application to Solvability of a System of Nonlinear Functional Integral Equations of Volterra Type

In this paper, we generalize the MeirKeeler condensing  operators  via a concept of the class of operators  $ O (f;.)$, that was given by Altun and Turkoglu [4], and apply this extension to obtain some tripled fixed point theorems.  As an application of this extension, we  analyze the existence of solution for a system of nonlinear functional integral equations of Volterra type. Finally,  we present an example  to show the effectiveness of our results. We use the technique of measure of noncompactness to obtain our results.
