چکیده
By using Riccati transformation technique, we will establish some new oscillation criteria for the even order neutral delay differential equations z t n q t f x σ t 0, t ≥ t0, where n is even, z t x t p t x τ t , 0 ≤ p t ≤ p0 < ∞, and q t ≥ 0. These oscillation criteria, at least in some sense, complement and improve those of Zafer 1998 and Zhang et al. 2010 . An example is considered to illustrate the main results.

Nonlinear oscillation of certain third-order neutral differential equation with distributed delay
The authors obtain necessary and sufficient conditions for the existence of oscillatory solutions with a specified asymptotic behavior of solutions to a nonlinear neutral differential equation with distributed delay of third order. We give new theorems which ensure that every solution to be either oscillatory or converges to zero asymptotically. Examples dwelling upon the importance of applicab...
متن کاملKamenev-Type Oscillation Criteria for Higher-Order Neutral Delay Dynamic Equations
In this paper, we are primarily concerned with the oscillation of solutions to higher-order dynamic equations. We first extend some recent results which have been obtained for second-order dynamic equations to even-order neutral delay dynamic equations. Our technique depends on making use of the Riccati substitution and the use of properties of the generalized Taylor monomials on time scales. W...
متن کاملOscillation of Second Order Neutral Delay Differential Equations
We present new oscillation criteria for the second order nonlinear neutral delay differential equation ( a (t) (y (t)+ p (t) y (t − τ))′)′ + q (t) |y (σ (t))|α−1 y (σ (t)) = 0, where t ≥ t0, τ, and α are positive constants and the functions p, q, a, σ ∈ C ([t0,∞) ,R) . Our results generalize and improve some known results for oscillation of second order neutral delay differential equations. Our...
متن کاملExistence and continuous dependence for fractional neutral functional differential equations
In this paper, we investigate the existence, uniqueness and continuous dependence of solutions of fractional neutral functional differential equations with infinite delay and the Caputo fractional derivative order, by means of the Banach's contraction principle and the Schauder's fixed point theorem.
