New Aspects for Non-Existence of Kneser Solutions of Neutral Differential Equations with Odd-Order [PDF]
Mathematics, 2020 Some new oscillatory and asymptotic properties of solutions of neutral differential equations with odd-order are established. Through the new results, we give sufficient conditions for the oscillation of all solutions of the studied equations, and this ...

Even-order differential equation with continuous delay: nonexistence criteria of Kneser solutions [PDF]
Advances in Difference Equations, 2021 In this paper, we study even-order DEs where we deduce new conditions for nonexistence Kneser solutions for this type of DEs. Based on the nonexistence criteria of Kneser solutions, we establish the criteria for oscillation that take into account the ...

Singular Kneser solutions of higher-order quasilinear ordinary differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2021 In this paper we give a new sufficient condition in order that all nontrivial Kneser solutions of the quasilinear ordinary differential equation \[ D(\alpha_n, \alpha_{n-1}, \dots, \alpha_1)x = (-1)^{n}p(t)|x|^{\beta}\mathrm{sgn}\,x, \quad t \geq a, \tag{
