Oscillation criteria for second order nonlinear neutral differential equations
This paper is concerned with the oscillation of second-order nonlinear neutral differential equations of the form [ r(t)[(x(t) + p(t)x(σ(t)))′]γ ]′ + f(t, x(τ(t))) = 0, by using a generalized Riccati’s technique and integral averaging technique, we establish new oscillation results which handle some cases not covered by known criteria.

متن کاملOscillation Criteria for Second-Order Nonlinear Neutral Delay Differential Equations
Some sufficient conditions are established for the oscillation of second-order neutral differential equation x t p t x τ t ′′ q t f x σ t 0, t ≥ t0, where 0 ≤ p t ≤ p0 < ∞. 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 ...

and Applied Analysis 3 where n ≥ 1 is odd. Grace 27 and Yan 28 obtained several sufficient conditions for the oscillation of solutions of higher-order neutral functional differential equation of the form x t cx t − h Cx t H n qxt − g Qx t G 0, t ≥ t0, 1.8 where q and Q are nonnegative real constants. Clearly, 1.6 is a special case of 1.1 . The purpose of this paper is to study the oscillation b...
