Impulsive system of ODEs with general linear boundary conditions [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
The paper provides an operator representation for a problem which consists of a system of ordinary differential equations of the first order with impulses at fixed times and with general linear boundary conditions \begin{gather} z'(t) = A(t)z(t) + f(t,z ...

Oscillation for higher order nonlinear ordinary differential equations with impulses

open access: yesElectronic Journal of Differential Equations, 2006
In this paper, we study the oscillation of solutions to higher order nonlinear ordinary differential equations with impulses. Several criteria for the oscillations of solutions are given.

Linearization of Impulsive Differential Equations with Ordinary Dichotomy [PDF]

open access: yesAbstract and Applied Analysis, 2014
This paper presents a linearization theorem for the impulsive differential equations when the linear system has ordinary dichotomy. We prove that when the linear impulsive system has ordinary dichotomy, the nonlinear systemx˙(t)=A(t)x(t)+f(t,x),t≠tk,Δx(tk)=A~(tk)x(tk)+f~(tk,x),k∈ℤ, is topologically conjugated tox˙(t)=A(t)x(t),t≠tk,Δx(tk)=A~(tk)x(tk),k ...

APPROXIMATION OF POSITIONAL IMPULSE CONTROLS FOR DIFFERENTIAL INCLUSIONS

open access: yesUral Mathematical Journal, 2022
Nonlinear control systems presented as differential inclusions with positional impulse controls are investigated. By such a control we mean some abstract operator with the Dirac function concentrated at each time. Such a control ("running impulse"), as a

Controllability of nonlinear ordinary differential equations with non-instantaneous impulses

open access: yesMathematical Modelling and Control, 2022
<abstract><p>In this paper, we consider controllability of the initial value problem with non-instantaneous impulse on ordered Banach spaces. We firstly give a solution expression for initial value problems with non-instantaneous impulses in ordered Banach Spaces by using Schauder fixed point theorem.

On nonclassical impulsive ordinary differential equations with nonlocal conditions

open access: yesInternational Journal of Analysis and Applications, 2019
Summary: Results on mild solutions of nonclassical differential equations with impulsive and nonlocal conditions are extended to a case when the nonlocal conditions are necessarily non Lipschitz and non compact.

On Exact Controllability of First-Order Impulsive Differential Equations

open access: yesAdvances in Difference Equations, 2010
Many dynamical systems have an impulsive dynamical behavior due to abrupt changes at certain instants during the evolution process. The mathematical description of these phenomena leads to impulsive differential equations.

Mixed-order impulsive ordinary and fractional differential equations with initial conditions [PDF]

open access: yesAdvances in Difference Equations, 2019
Dans cet article, en utilisant l'idée d'intervalles séparés dans les équations impulsives non instantanées, nous commençons l'étude des problèmes de valeur initiale pour les équations différentielles ordinaires et fractionnaires d'ordre mixte avec des effets impulsifs instantanés.

The remarkable effectiveness of time-dependent damping terms for second order evolution equations [PDF]

open access: yes, 2015
We consider a second order linear evolution equation with a dissipative term multiplied by a time-dependent coefficient. Our aim is to design the coefficient in such a way that all solutions decay in time as fast as possible.
