Mittag-Leffler Type Stability of Delay Generalized Proportional Caputo Fractional Differential Equations: Cases of Non-Instantaneous Impulses, Instantaneous Impulses and without Impulses

Symmetry, 2022
In this paper, nonlinear differential equations with a generalized proportional Caputo fractional derivative and finite delay are studied in this paper. The eventual presence of impulses in the equations is considered, and the statement of initial value problems in three cases is defined: namely non-instantaneous impulses, instantaneous impulses and no

Infinitely many solutions to fractional differential equations with instantaneous and non-instantaneous impulses [PDF]

, 2021
The goal of this paper is to study fractional differential equations involving instantaneous and non-instantaneous impulses with Sturm-Liouville boundary conditions. By using critical point theory and variational approach, infinitely many solutions are obtained. The interesting point is that the potential has an oscillating asymptotic behavior.

Variational approach to differential equations with not instantaneous impulses

Applied Mathematics Letters, 2017
In this article, authors investigate non-instantaneous impulsive differential equations \[ \begin{cases} -u''(t)=\sigma_i(t),\quad t \in (s_i, t_{i+1}],\; i = 0, 1, \dots ,N,\\ u'(t) = \alpha_i,\quad t \in (t_i, s_i],\; i = 1, 2, \dots ,N,\\ u'(s^+_i ) = u'(s^-_i ),\quad i=1,2,\dots ,N,\\ u(0) = u(T) = 0,\quad u'(0) = \alpha_0, \end{cases} \eqno{(1)} \]

Caputo–Fabrizio fractional differential equations with non instantaneous impulses

Rendiconti del Circolo Matematico di Palermo Series 2, 2021
<abstract><p>The subjuct of this paper is the existence of solutions for a class of Caputo-Fabrizio fractional differential equations with instantaneous impulses. Our results are based on Schauder's and Monch's fixed point theorems and the technique of the measure of noncompactness.

Mild solution of fractional order differential equations with not instantaneous impulses

Open Mathematics, 2015
In this paper, we investigate the boundary value problems of fractional order differential equations with not instantaneous impulse. By some fixed-point theorems, the existence results of mild solution are established.

Instantaneous and Noninstantaneous Impulsive Integrodifferential Equations in Banach Spaces

Abstract and Applied Analysis, 2020
This paper deals with some existence of mild solutions for two classes of impulsive integrodifferential equations in Banach spaces. Our results are based on the fixed point theory and the concept of measure of noncompactness with the help of the resolvent operator. Two illustrative examples are given in the last section.

Comparison of thrusts imparted by a magnetron sputtering source operated in DC and high power impulse modes

AIP Advances, 2021
The thrusts induced by the 45-mm-diameter DC and high power impulse magnetron sputtering [DC magnetron sputtering (DCMS) and high power impulse magnetron sputtering (HiPIMS)] sources are assessed by using the pendulum thrust balance, where the ...
