Existence and Integral Representation of Scalar Riemann-Liouville Fractional Differential Equations with Delays and Impulses [PDF]

open access: yes, 2020
Nonlinear scalar Riemann-Liouville fractional differential equations with a constant delay and impulses are studied and initial conditions and impulsive conditions are set up in an appropriate way.

Eventual stability and eventual boundedness for impulsive differential equations with “supremum”

open access: yesMathematical Modelling and Analysis, 2011
Eventual stability and eventual boundedness for nonlinear impulsive differential equations with supremums are studied. The impulses take place at fixed moments of time. Piecewise continuous Lyapunov functions have been applied.

Bifurcation of Bounded Solutions of Impulsive Differential Equations [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2016
In this article, we examine nonautonomous bifurcation patterns in nonlinear systems of impulsive differential equations. The approach is based on Lyapunov–Schmidt reduction applied to the linearization of a particular nonlinear integral operator whose zeroes coincide with bounded solutions of the impulsive differential equation in question. This leads

About differential inequalities for nonlocal boundary value problems with impulsive delay equations [PDF]

open access: yes, 2015
summary:We propose results about sign-constancy of Green's functions to impulsive nonlocal boundary value problems in a form of theorems about differential inequalities. One of the ideas of our approach is to construct Green's functions of boundary value

A Survey on Oscillation of Impulsive Ordinary Differential Equations [PDF]

open access: yesAdvances in Difference Equations, 2010
The authors make a fundamental survey on oscillation of first- and second-order of linear, half-linear, super-half-linear and nonlinear impulse differential equations. The Sturmian theory for second-order linear impulse equations is discussed, too.

On the solution of \(\mathcal{T}-\)controllable abstract fractional differential equations with impulsive effects

open access: yesCubo, 2023
In this research article, we delimitate the definition of mild solution for abstract fractional differential equations with state-dependent delay (AFDEw/SDD) of order \(\alpha\in(1,2)\) with impulsive effects and compare the solution to the second-order ...

On the fractional differential equations with not instantaneous impulses

open access: yesOpen Physics, 2016
AbstractBased on some previous works, an equivalent equations is obtained for the differential equations of fractional-orderq∈(1, 2) with non-instantaneous impulses, which shows that there exists the general solution for this impulsive fractional-order systems. Next, an example is used to illustrate the conclusion.

Second-Order Nonlinear Impulsive Integro-Differential Equations of Mixed Type and Optimal Controls in Fractional Power Spaces

open access: yesAbstract and Applied Analysis, 2010
A class of second-order nonlinear impulsive integro-differential equations of mixed type whose principal part is given by time-varying generating operators in fractional power spaces is considered. We introduce the reasonable PC-α-mild solution of second-
