چکیده
Abstract An interesting point in studying the oscillatory behavior of solutions delay differential equations is abbreviation conditions that ensure oscillation all solutions, especially when noncanonical case. Therefore, this study aims to reduce fourth-order with a operator. Moreover, approach used gives more accurate results applied some special cases, as we explained examples.

متن کاملSurvey of Oscillation Criteria for First Order Delay Differential Equations
In this paper, we discuss the oscillatory behavior of first order delay differential equations of the form: y′(t) + p(t)y(τ(t)) = 0, t ≥ T, where p and T are continuous functions defined on [T,∞), p(t) > 0, τ(t) < t for t ≥ T, τ(t) is nondecreasing and lim t→∞ τ(t) = ∞. We present best possible conditions for the oscillation of all solutions for this equation.

The objective of this article is to study the oscillation properties of the solutions to the fourth-order linear trinomial delay differential equation y(t) + p(t)y′(t) + q(t)y(τ(t)) = 0. Applying suitable comparison principles, we present new criteria for oscillation. In contrast with the existing results, we establish oscillation of all solutions, and essentially simplify the examination proce...
متن کاملOn Oscillation Criteria for Third Order Nonlinear Delay Differential Equations
In this paper we are concerned with the oscillation of third order nonlinear delay differential equations of the form ( r2 (t) ( r1 (t)x′ )′)′ + p (t)x′ + q (t) f (x (g (t))) = 0. We establish some new sufficient conditions which insure that every solution of this equation either oscillates or converges to zero.
