NONOSCILLATORY SOLUTIONS OF DELAY DIFFERENCE EQUATIONS WITH OSCILLATING COEFFICIENTS
Demonstratio Mathematica, 2003 Using the analogy with differential equations with deviated argument the authors study non-oscillatory solutions of the scalar equation \[ \Delta y_k = P^o_ky_k + \sum_1^nP^i_ky_{k-K^i_k} \] with bounded coefficients satisfying an oscillation condition.

Nonoscillatory solutions of neutral differential equations
Hiroshima Mathematical Journal, 1990 The paper deals with the neutral ODE \((*)\quad (d^ n/dt^ n)(x(t)- h(t)x(s(t)))+kp(t)f(x(g(t)))=0,\) \(n\geq 2\), \(k^ 2=1\), \(s(t)0\) for \(u\neq 0\), g(t)\(\to \infty\), \(t\to \infty\). A systematic study of the structure of all nonoscillatory solutions of the equation (*) is given.

Remarks on the existence of nonoscillatory solutions of half-linear ordinary differential equations, II [PDF]
, 2021 summary:We consider the half-linear differential equation of the form \[ (p(t)|x^{\prime }|^{\alpha }\mathrm{sgn}\,x^{\prime })^{\prime } + q(t)|x|^{\alpha }\mathrm{sgn}\,x = 0\,, \quad t \ge t_{0} \,, \] under the assumption that $p(t)^{-1/\alpha }$ is ...

Delayed Parasitism and Population Cycles in Mosquito–Water Mite Systems
Complexity, Volume 2026, Issue 1, 2026.This study uses a delay differential equation (DDE) model that takes into account both parasitism and predation effects to examine the dynamic interactions between water mites and mosquito populations. The proposed DDE model uniquely captures the dual ecological role of water mites as both parasites and predators of mosquitoes through biologically ...

Existence of nonoscillatory solutions to nonlinear higher-order neutral dynamic equations
Advances in Difference Equations, 2020 We investigate the existence of different types of nonoscillatory solutions to a class of higher-order nonlinear neutral dynamic equations on a time scale. Two examples are provided to show the significance of the conclusions.

Nonoscillatory solutions of neutral delay differential equations [PDF]
Bulletin of the Australian Mathematical Society, 1993 Consider the following neutral delay differential equationwherep∈R,τ∈ (0, ∞), δ ∈R+= (0, ∞) and Q ∈ (C([t0, ∞),R). We show that ifthen Equation (*)has a nonoscillatory solution whenp≠ –1. We also deal in detail with a conjecture of Chuanxi, Kulenovic and Ladas, and Györi and Ladas.

Impact of Grid Strength on the Transient Dynamics of Droop‐ and VSM‐Based Grid‐Forming Converters
International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.With the increasing use of converter‐based resources, it has become more crucial to comprehend the dynamic interaction between grid‐forming (GFM) control strategies and power system transients under different grid strengths. The transient performance of droop‐controlled and virtual synchronous machine (VSM)–based GFM converters exposed to significant ...
