Abstract

In this paper, using a simple and classical application of the Leray-Schauder degree theory, we study the existence of solutions of the following boundary value problem for functional differential equations x(t)+f(t,xt,x(t))=0,   t[0,T]x0+αx(0)=hx(T)+βx(T)=η where fC([0,T]×Cr×n,n), hCr, ηn and α, β, are real constants.
