Oscillation and non-oscillation of some neutral differential equations of odd order [PDF]
International Journal of Mathematics and Mathematical Sciences, 1992 An existence criterion for nonoscillatory solution for an odd order neutral differential equation is provided. Some sufficient conditions are also given for the oscillation of solutions of some nth order equations with nonlinearity in the neutral term.

Note on a non-oscillation theorem of Atkinson
Electronic Journal of Differential Equations, 2004 We present a general non-oscillation criterion for a second order two-term scalar nonlinear differential equation in the spirit of a classic result by Atkinson [1]. The presentation is simpler than most and can serve to unify many such criteria under one

Non-oscillating Paley-Wiener functions [PDF]
Journal d'Analyse Mathématique, 2001 A real Paley-Wiener function (PW-function) is an entire function, \(f\), of exponential type such that \(f\in L_2(\mathbb R)\) and \(f(\mathbb R)\subset \mathbb R\). J. R. Higgins posed the question whether or not some derivative of an arbitrary real Paley-Wiener function has infinitely many real zeros.

Non-oscillating power spectra in loop quantum cosmology [PDF]
Classical and Quantum Gravity, 2020 Abstract We characterize in an analytical way the general conditions that a choice of vacuum state for the cosmological perturbations must satisfy to lead to a power spectrum with no scale-dependent oscillations over time. In particular, we pay special attention to the case of cosmological backgrounds governed by effective loop ...

Differential inequality and non-oscillation of fourth order differential equation
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 The oscillatory theory of fourth order differential equations has not yet been developed well enough. Theresults are known only for the case when the coefficients of differential equations are power functions.

Non-Oscillating solutions of a generalized system of ODEs with derivative terms [PDF]
Nonautonomous Dynamical Systems, 2021 Abstract We consider a system of ODEs of mixed order with derivative terms appearing in the non-linear function and show the existence of a solution which does not oscillate for such system. We applied the fixed point technique to show that under certain conditions there exists at least one solution to the system which is not only non ...

Oscillation of Emden–Fowler-Type Neutral Delay Differential Equations
Axioms, 2020 In this work, we consider a type of second-order functional differential equations and establish qualitative properties of their solutions. These new results complement and improve a number of results reported in the literature.
