Abstract
The nonautonomous delay differential systemx(t) = f(t, x(t - tau)),is considered, where tau 0, f : R x R-n - R-n is a continuous vector function such thatf(t + 4 tau, x) = f(t, x), f(t, x) = del F-x(t, x).Using the critical point theory, the conditions ensuring the existence of a nontrivial 4 tau-periodic solution of that system are established in the case, where F(t, x) is superquadratic in x.
