EXISTENCE OF SOLUTION FOR SYSTEM OF INTEGRAL EQUATIONS AND FUNCTIONAL EQUATIONS THROUGH NON-NEGATIVE FUNCTION WITH PROPERTY OF ONENESS

Abstract

In this article, we define the notion of a non-negative function satisfying property of oneness. Utilizing this concept, certain unified fixed point results are established. Furthermore generalized φ-contractions mapping and some fixed point results in the framework of symmetric space are also presented. Some well-known results from the existence literature are obtained through our introduced setting. Results are substantiated by some innovative examples with the aid of visualization of surfaces. Moreover applications of obtained theory for the existence for the system of integral equations as well as for the system of functional equations occurred in dynamic programming are also presented.
