Nonoscillation of Linear Difference Systems

open access: yesJournal of Mathematical Analysis and Applications, 1994
For the system \(\Delta x = A(t)x\) with \(\Delta x(t) = x(t + 1) - x(t)\), similar nonoscillatory conditions are obtained as in the well known case \(x'(t) = A(t)x\), cf. \textit{S. Friedland} [Mem. Am. Math. Soc. 176 (1976; Zbl 0348.34023)]. In particular, the two-dimensional case is considered in detail.

The Oscillatory of Linear Conformable Fractional Differential Equations of Kamenev Type

open access: yesDiscrete Dynamics in Nature and Society, Volume 2020, Issue 1, 2020., 2020
In this paper, the oscillatory of the Kamenev‐type linear conformable fractional differential equations in the form of ptyα+1tα+yα+1t+qtyt=0 is studied, where t ≥ t0 and 0 < α ≤ 1. By employing a generalized Riccati transformation technique and integral average method, we obtain some oscillation criteria for the equation.

Nonoscillations in retarded systems

open access: yesJournal of Mathematical Analysis and Applications, 2005
Consider the equation \[ x(t)+ \int^0_{-1} d[\nu(\theta)]x(t- r(\theta))= 0,\tag{1} \] where \(x(t)\in \mathbb{R}^n\), \(r\in C([-1,0], \mathbb{R}_+)\), and \(\nu(\theta)\) is a real \(n\times n\) matrix valued function of bounded variation on \([-1, 0]\).

On the Asymptotic Behavior of a Class of Second-Order Non-Linear Neutral Differential Equations with Multiple Delays

open access: yesAxioms, 2020
In this work, we present some new sufficient conditions for the oscillation of a class of second-order neutral delay differential equation. Our oscillation results, complement, simplify and improve recent results on oscillation theory of this type of non-

On positiveness of the fundamental solution for a linear autonomous differential equation with distributed delay

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
We present necessary and sufficient conditions for the nonoscillation of the fundamental solutions to a linear autonomous differential equation with distributed delay. The conditions are proposed in both the analytic and geometric forms.

Oscillation and Nonoscillatory Criteria of Higher Order Dynamic Equations on Time Scales

open access: yesMathematics, 2022
In this paper, we consider two universal higher order dynamic equations with several delay functions. We will establish two oscillatory criteria of the first equation and a sufficient and necessary condition for the second equation with a nonoscillatory ...

On Constants in Nonoscillation Criteria for Half-Linear Differential Equations

open access: yesAbstract and Applied Analysis, 2011
We study the half-linear differential equation (r(t)Φ(x′))′+c(t)Φ(x)=0, where Φ(x)=|x|p−2x, p>1. Using the modified Riccati technique, we derive new nonoscillation criteria for this equation.
