Periodic solutions for functional differential equations with infinite lead and delay
The problem of the existence of periodic solutions to functional differential equations with infinite lead and delay is discussed. An existence theorem for the Cauchy problem for such equations is given, too. The results are based upon the combination of degree theory, Lyapunov's direct method, and differential inequality techniques.
