摘要：

This paper is concerned with the oscillatory behavior of solutions of the nth-order nonlinear differential equations with an advanced argument x((n))(t) + delta q(t)x(lambda) (g(t)) = 0, t >= t(0) >= 0, where n >= 2 is even or odd and delta = +/- 1. Here q(t) > 0, g(t) >= t, and lambda is the ratio of odd positive integers. The results are illustrated with an example. (C) 2020 Elsevier Ltd. All rights reserved.
