Abstract:A kind of periodic solution of higher order functional differential equations with delay is studied x(n)(t)+h(x′(t))x(t)+f(x(t))x′(t)+g(x(t-τ(t)))=p(t),the sufficient conditions on the existence of periodic solutions are obtained.
Keywords:differential equation with delay  periodic solution  coincidence degree
