On generalized coupled fixed points with applications to the solvability of coupled systems of nonlinear quadratic integral equations

摘要

In this paper, we introduce the notion of generalized coupled fixed points and, as a consequence of Darbo's fixed point theorem associated to an abstract measure of noncompactness, we present a result about the existence of this class of coupled fixed points in Banach spaces. As an application, we investigate the existence of solutions for a class of coupled systems of nonlinear quadratic integral equations of Volterra type.
