Abstract

Some sufficient conditions are established for the oscillation of second-order neutral differential equation , , where . 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).

Highlights

  • The oscillatory behavior of differential equations has been the subject of intensive study; we refer to the articles 1–13 ; Especially, the study of the oscillation of neutral delay differential equations is of great interest in the last three decades; see for example 14–38 and references cited therein

  • Second-order neutral delay differential equations have applications in problems dealing with vibrating masses attached to an elastic bar and in some variational problems see 39

  • This paper is concerned with the oscillatory behavior of the second-order neutral delay differential equation xt ptxτt qtfxσt 0, t ≥ t0, 1.1 where p, q ∈ C t0, ∞, R, f ∈ C R, R
