摘要
Some sufficient conditions are established for the oscillation of second-order neutral differential equation (x(t) + p(t)x(tau(t)))'' + q(t)f(x(sigma(t))) = 0, t >= t(0), where 0 <= p(t) <= p(0) < +infinity. The results complement and improve those of Grammatikopoulos et al. Ladas, A. Meimaridou, Oscillation of second-order neutral delay differential equations, Rat. Mat. 1 (1985), Grace and Lalli (1987), Ruan (1993), H.J.Li (1996), H.J.Li (1997), Xu and Xia (2008).
