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.

Random Fuzzy Differential Equations with Impulses [PDF]

open access: yesComplexity, 2017
We consider the random fuzzy differential equations (RFDEs) with impulses. Using Picard method of successive approximations, we shall prove the existence and uniqueness of solutions to RFDEs with impulses under suitable conditions. Some of the properties of solution of RFDEs with impulses are studied.

Regularity Coefficients for Impulsive Differential Equations

open access: yesThe Quarterly Journal of Mathematics, 2020
Abstract For a linear impulsive differential equation, we introduce a Lyapunov regularity coefficient following as far as possible the non-impulsive case. We recall that a regularity coefficient is a quantity that characterizes the Lyapunov regularity of the dynamics.

Non-autonomous bifurcation in impulsive systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
This is the first paper which considers non-autonomous bifurcations in impulsive differential equations. Impulsive generalizations of the non-autonomous pitchfork and transcritical bifurcation are discussed. We consider scalar differential equation with

Asymptotic Behavior of Impulsive Differential Equations

open access: yesRocky Mountain Journal of Mathematics, 1996
This is one of the first works devoted to the study of asymptotic behaviour of solutions of the following impulsive system: \(x' = f(t,x)\), \(t \neq t_i\), \(\Delta x(t_i) = \varphi_i (x(t_i))\), \(t_i \to + \infty\), \((t,x) \in \mathbb{R}_+ \times \mathbb{R}^n\).

Oscillation Criteria for Solutions of Neutral Differential Equations of Impulses Effect with Positive and Negative Coefficients

open access: yesمجلة بغداد للعلوم, 2020
In this paper, some necessary and sufficient conditions are obtained to ensure the oscillatory of all solutions of the first order impulsive neutral differential equations. Also, some results in the references have been improved and generalized.
