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

Nonoscillations in retarded systems
Journal 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 Constants in Nonoscillation Criteria for Half-Linear Differential Equations
Abstract 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.

Antiprincipal solutions at infinity for symplectic systems on time scales
Electronic Journal of Qualitative Theory of Differential Equations, 2020 In this paper we introduce a new concept of antiprincipal solutions at infinity for symplectic systems on time scales. This concept complements the earlier notion of principal solutions at infinity for these systems by the second author and Šepitka ...

Necessary and Sufficient Conditions for Oscillation of Nonlinear Neutral Difference Systems of dim-2
Nonautonomous Dynamical Systems, 2022 This work is concerned about the necessary and sufficient conditions for oscillation of solutions of 2-dimensional nonlinear neutral delay difference systems of the form: Δ[x(n)+p(n)x(n−m)y(n)+p(n)y(n−m)]=[a(n)b(n)c(n)d(n)] [f(x(n−α))g(y(n−β))],\Delta ...
