Addendum to ``Ulam–Hyers stability and exponentially dichotomic equations in Banach spaces'' [Electron. J. Qual. Theory Differ. Equ. 2023, No. 8, 1–10]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2023
We add relevant references about which we learned after the completion of the initial work. We mainly show how the concept of exponential trichotomy can successfully replace the one of exponential dichotomy in some results from the paper in the title.

Datko-type theorems concerning asymptotic behaviour of exponential type in mean [PDF]

open access: yesOpuscula Mathematica
In this paper, we study the concept of exponential (in)stability in mean for stochastic skew-evolution semiflows, in which the exponential (in)stability in the classical sense is replaced by an average with respect to a probability measure.

Almost sure and moment exponential stability in the numerical simulation of stochastic differential equations [PDF]

open access: yes, 2007
Relatively little is known about the ability of numerical methods for stochastic differential equations (SDEs) to reproduce almost sure and small-moment stability.

Stability of hybrid stochastic retarded systems [PDF]

open access: yes, 2008
-In the past few years, hybrid stochastic retarded systems (also known as stochastic retarded systems with Markovian switching), including hybrid stochastic delay systems, have been intensively studied. Among the key results, Mao et al.

The Convergence and MS Stability of Exponential Euler Method for Semilinear Stochastic Differential Equations

open access: yesAbstract and Applied Analysis, 2012
The numerical approximation of exponential Euler method is constructed for semilinear stochastic differential equations (SDEs). The convergence and mean-square (MS) stability of exponential Euler method are investigated. It is proved that the exponential

Delay-dependent robust stability of stochastic delay systems with Markovian switching [PDF]

open access: yes, 2009
In recent years, stability of hybrid stochastic delay systems, one of the important issues in the study of stochastic systems, has received considerable attention. However, the existing results do not deal with the structure of the diffusion but estimate

Global exponential stabilization of freeway models [PDF]

open access: yesInternational Journal of Robust and Nonlinear Control, 2015
SummaryThis work is devoted to the construction of feedback laws, which guarantee the robust global exponential stability of the uncongested equilibrium point for general discrete‐time freeway models. The feedback construction is based on a control Lyapunov function approach and exploits certain important properties of freeway models.

Fractional Stability of Trunk Acceleration Dynamics of Daily-Life Walking: Toward a Unified Concept of Gait Stability

open access: yesFrontiers in Physiology, 2017
Over the last decades, various measures have been introduced to assess stability during walking. All of these measures assume that gait stability may be equated with exponential stability, where dynamic stability is quantified by a Floquet multiplier or ...

On the Stability of Some Exponential Polynomials

open access: yesJournal of Mathematical Analysis and Applications, 1997
The authors deal with the transcendental equation of the type \[ (z+ pz+ q)\exp(\tau z)+ rz=0, \] where \(p\), \(q\), \(r\), \(\mathbb{R}\), \(\tau, p>0\), \(q>0\), \(r=0\), \(n=0,1,2\). The main results are concerned with the case \(n=0\), which is important in the stability theory of delay.

A unified framework of rapid exponential stability and optimal feedback control for nonlinear systems

open access: yesAdvances in Mechanical Engineering, 2019
A novel framework of rapid exponential stability and optimal feedback control is investigated and analyzed for a class of nonlinear systems through a variant of continuous Lyapunov functions and Hamilton–Jacobi–Bellman equation.
