On the Nonoscillation of Second-Order Neutral Delay Differential Equation with Forcing Term

open access: yesDiscrete Dynamics in Nature and Society, 2008
This paper is concerned with nonoscillation of second-order neutral delay differential equation with forcing term. By using contraction mapping principle, some sufficient conditions for the existence of nonoscillatory solution are established.

Oscillation and global asymptotic stability of a neuronic equation with two delays

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2008
In this paper we study the oscillatory and global asymptotic stability of a single neuron model with two delays and a general activation function. New sufficient conditions for the oscillation and nonoscillation of the model are given.

Oscillation and Nonoscillation of Asymptotically Almost Periodic Half-Linear Difference Equations

open access: yesAbstract and Applied Analysis, 2013
We analyse half-linear difference equations with asymptotically almost periodic coefficients. Using the adapted Riccati transformation, we prove that these equations are conditionally oscillatory.

New oscillation criteria for third order nonlinear functional differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
The authors consider the general third order functional differential equation \begin{align*} \left(a_{2}(\nu)\left[\left(a_{1}(\nu)\left(x'(\nu)\right)^{\alpha_{1}}\right)'\right]^{\alpha_{2}}\right)'+q(\nu) x^{\beta}(\tau(\nu))=0,\qquad\nu\geq \nu_{0},

On oscillation of a food-limited population model with time delay

open access: yesAbstract and Applied Analysis, 2003
For a scalar nonlinear delay differential equation Ṅ(t) = r(t)N(t)(K − N(h(t)))/(K + s(t)N(g(t))),r(t) ≥ 0, h(t) ≤ t, g(t) ≤ t and some generalizations of this equation, we establish explicit oscillation and nonoscillation conditions.

More Effective Criteria for Testing the Oscillation of Solutions of Third-Order Differential Equations

open access: yesAxioms
In the current paper, we aim to study the oscillatory behavior of a new class of third-order differential equations. In the present study, we are interested in a better understanding of the relationships between the solutions and their derivatives.

Oscillation and nonoscillation of two terms linear and half-linear equations of higher order

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2010
In this paper we investigate the properties of nonoscillation for the equation $$(-1)^{n}(\rho(t)|y^{(n)}|^{p-2}y^{(n)})^{(n)}-v(t)|y|^{p-2}y=0,$$ where ...
