摘要
In this article, we study the oscillation and asymptotic behavior of solutions to the nonlinear delay differential equation x((n+3))(t) + p(t)x((n))(t) + q(t)f(x(g(t))) = 0. By using a generalized Riccati transformation and an integral averaging technique, we establish sufficient conditions for all solutions to oscillate, or to converge to zero. Especially when the delay has the form g(t) = alpha t - tau, we provide two convenient oscillatory criteria. Some examples are given to illustrate our results.
