Exploring Gas Evolution Oscillators: Mechanisms and Applications. [PDF]

Chemphyschem
Explore the rhythms of gas evolution oscillators, i. e. systems showing oscillatory delivery of gas sustained by simple reactions yielding gaseous products in a liquid mixture, due to nucleation and supersaturation phenomena. We delve into their mechanisms and their potential to control chemical processes, with a focus on sustainable energy ...

Oscillation and Asymptotic Behavior of Three-Dimensional Third-Order Delay Systems

International Journal of Differential Equations, 2023
In this paper, oscillation and asymptotic behavior of three-dimensional third-order delay systems are discussed. Some sufficient conditions are obtained to ensure that every solution of the system is either oscillatory or nonoscillatory and converges to ...

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.

Existence of Nonoscillatory Solutions of Higher-Order Neutral Differential Equations with Distributed Coefficients and Delays

Discrete Dynamics in Nature and Society, 2016
We consider the existence of nonoscillatory solutions of higher-order neutral differential equations with distributed coefficients. We use the Banach contraction principle to obtain new sufficient condition for the existence of nonoscillatory solutions.

On nonoscillatory solutions of a nonlinear differential equation [PDF]

Proceedings of the American Mathematical Society, 1972
Sufficient conditions are given which insure that all nonoscillatory solutions of (p(t)x')'+h(x)x'+q(t)g(x) =f (t) tend to zero as t tends to infinity. In this paper we examine the behavior of the nonoscillatory solutions of the equation (1) (p(t)x')' + h(x)x' + q(t)g(x) = f(t) where p, q, andf are real valued and continuous for t >0 and h and g are ...
