摘要：
In this paper, the authors consider the existence of periodic solutions for a kind of second neutral functional differential equation as follows: (x(t) - cx(t - tau))'' = g(t, x(t - mu(t))) + e(t), in the critical case vertical bar c vertical bar = 1. By employing Mawhin's continuation theorem and some analysis techniques, some new results are obtained.
