摘要
We consider the Lienard equation x ''(t) + f(1)(x(t))(x'(t))(2) + f(2)(x(t))x'(t)+g(0)(x(t)) + Sigma(m)(j=1)g(j)(x(t-tau(j) (t))) = p(t), where f(1), f(2), g(1) and g(2) are continuous functions, the delays tau(j) (t) >= 0 are bounded continuous, and p(t) is a bounded continuous function. We obtain sufficient conditions for all solutions and their derivatives to be bounded.
