Covariant functors and asymptotic stability

open access: yesJournal of Algebra, 2017
Let R be a commutative Noetherian ring, I and J ideals of R and M a finitely generated R-module. Let F be a covariant R-linear functor from the category of finitely generated R-modules to itself. We first show that if F is coherent, then the sets of associated primes of F(M/I^n M) and F(I^n-1 M / I^n M) and the J-depths of F(M/I^n M) and F(I^n-1 M / I ...

A Sufficient Condition for Asymptotic Stability of Discrete-Time Interval System with Delay

open access: yesDiscrete Dynamics in Nature and Society, 2008
The asymptotic stability of discrete-time interval system with delay is discussed. A new sufficient condition for preserving the asymptotic stability of the system is presented by means of the inequality techniques.

STABILITY AND STABILIZATION OF NONLINEAR DYNAMICAL SYSTEMS

open access: yesASEAN Journal on Science and Technology for Development, 2017
Exponential and asymptotic stability for a class of nonlinear dynamical systems with uncertainties is investigated.  Based on the stability of the nominal system, a class of bounded continuous feedback controllers is constructed.

The asymptotic stability of difference equations

open access: yesApplied Mathematics Letters, 2000
The paper discusses the stability properties of the linear delay difference equation \[ x_{n+1}-x_n=-a_nx_{n-k} , \tag{1} \] where \(a_n\geq 0\) and \(k\geq 1\). As the main result it is proved that if \[ \sum_{n=0}^{\infty}a_n=\infty \tag{"(C1)"} \] and \[ \underset{n\to\infty}\limsup \sum_{j=n-2k}^{n-1 ...

Asymptotic consensus of hybrid multi-agent systems considering network attacks

open access: yesScientific Reports
This paper focuses on the problem of active defense and achieving asymptotic consensus control in hybrid multi-agent systems under network attacks. Considering the influence of Byzantine nodes, on the basis of the theory of mimic defense, a deep dynamic ...

A weak invariance principle and asymptotic stability for evolution equations with bounded generators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
If V is a Lyapunov function of an equation du/dt=u′=Zu in a Banach space then asymptotic stability of an equilibrium point may be easily proved if it is known that sup(V′)

Positivity and Asymptotic Stability of Descriptor Linear Systems with Regular Pencils

open access: yesArchives of Control Sciences, 2014
The positivity and asymptotic stability of the descriptor linear continuous-time and discrete-time systems with regular pencils are addressed. Necessary and sufficient conditions for the positivity and asymptotic stability of the systems are established ...
