Hyers-Ulam stability of exact second-order linear differential equations [PDF]

open access: yes, 2012
In this article, we prove the Hyers-Ulam stability of exact second-order linear differential equations. As a consequence, we show the Hyers-Ulam stability of the following equations: second-order linear differential equation with constant coefficients ...

Modeling measles transmission in adults and children: Implications to vaccination for eradication [PDF]

open access: yesInfectious Disease Modelling
Despite the availability of successful vaccines, measles outbreaks have occurred frequently in recent years, presumably due to the lack of proper vaccination implementation.

Addendum to asymptotic stability in differential equations with unbounded delay [PDF]

open access: yes, 2001
This addendum concerns the paper of the above title found in EJQTDE No. 13 (1999). Throughout that paper was the tacit assumption that the coefficient functions $h(t)$, $b(t)$, and $C(t)$ are all continuous on their respective domains. Every result, as

Modeling Wolbachia infection frequency in mosquito populations via a continuous periodic switching model

open access: yesAdvances in Nonlinear Analysis, 2023
In this article, we develop a continuous periodic switching model depicting Wolbachia infection frequency dynamics in mosquito populations by releasing Wolbachia-infected mosquitoes, which is different from the discrete modeling efforts in the literature.

Delay-Dependent Stability Conditions for Non-autonomous Functional Differential Equations with Several Delays in a Banach Space

open access: yesNonautonomous Dynamical Systems, 2021
Let Bj(t) (j = 1,..., m) and B(t, τ) (t ≥ 0, 0 ≤ τ ≤ 1) be bounded variable operators in a Banach space. We consider the equation u′(t)=∑k=1mBk(t)u(t-hk(t))+∫01B(t,τ)u(t-h0(τ))dτ    (t≥0),u'\left( t \right) = \sum\limits_{k = 1}^m {{B_k}\left( t \right)u\

Mean square exponential stability of stochastic function differential equations in the G-framework

open access: yesOpen Mathematics, 2023
This research focuses on the stochastic functional differential equations driven by G-Brownian motion (G-SFDEs) with infinite delay. It is proved that the trivial solution of a G-SFDE with infinite delay is exponentially stable in mean square. An example

Semi-Hyers-Ulam-Rassias stability for an integro-differential equation of order 𝓃

open access: yesDemonstratio Mathematica, 2023
The Laplace transform method is applied in this article to study the semi-Hyers-Ulam-Rassias stability of a Volterra integro-differential equation of order n, with convolution-type kernel.

Dynamics of a diffusive delayed competition and cooperation system

open access: yesOpen Mathematics, 2020
In this manuscript, we first consider the diffusive competition and cooperation system subject to Neumann boundary conditions without delay terms and get the conclusion that the unique positive constant equilibrium is locally asymptotically stable. Then,
