AN EXISTENCE THEOREM OF TRIPLED FIXED POINT FOR A CLASS OF OPERATORS ON BANACH SPACE WITH APPLICATIONS
B. Matani, J. R. Roshan

Abstract

In this paper, using the technique of measure of noncompactness, we prove some theorems on tripled fixed points for a class of operators in a Banach space. Also as an application, we discuss the existence of solution for a class of systems of nonlinear functional integral equations. Finally a concrete example illustrating the mentioned applicability is also included.
