Almost periodic functions serve as a powerful conceptual framework in analysing differential equations whose coefficients or forcing terms exhibit recurrent behaviour over time. Rooted in the ...

ABSTRACT: In this paper, we consider an impulsive competitive system with infinite delay and diffusion. Firstly, on basis of inequality estimation techniques and comparison theorem of impulsive ...

School of Mathematics and Physics, China University of Geosciences, Wuhan, China. Since fractional calculus is well-suited to characterizing materials and processes with memory and genetic properties, ...

Abstract: Conditions for strong stability and the existence of almost periodic solutions of systems of impulsive differential equations with impulsive effect at fixed moments are obtained. The ...

Abstract: This paper deals with the response of a stratified cold plasma to an infinite plane impulsive electromagnetic wave incident vertically on the ionization. The impulse response is found by ...
