摘要：

We obtain sufficient conditions for the existence of periodic solutions of the following third order nonlinear functional differential equations x'''(t) + ax''(2k-1) (t) + bx'(2k-1) (t) + x(2k-1) (t) + g (t, x(t - tau(1)), x'(t - tau(2))) = p(t) = p(t + 2pi). Our approach is based on the continuation theorem of the coincidence degree, and the a priori estimate of periodic solutions. (C) 2004 Published by Elsevier Inc.
