The solvability of a class of system of nonlinear integral equations via measure of noncompactness

Habibollah Nasiri, Jamal Rezaei Roshan


We propose a new notion of contraction mappings for two class of functions involving measure of noncompactness in Banach space. In this regard we present some theory and results on the existence of tripled fixed points and some basic Darbo's type fixed points for a class of operators in Banach spaces. Also as an application we discuss the existence of solutions for a general system of nonlinear functional integral equations which satisfy in new certain conditions . Further we give an example to verify the effectiveness and applicability of our results.
