Abstract

In this article, we use fixed-point methods and measure of noncompactness theory to focus on the problem of establishing the existence of at least a solution for the following functional integral equation

u(t)=g(t,u(t))+0tG(t,s,u(s))ds,t[0,+[, in the space of all bounded and continuous real functions on R+, under suitable assumptions on g and G. Also, we establish an extension of Darbo’s fixed-point theorem and discuss some consequences.
