Almost periodic skew-symmetric differential systems [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
We analyse solutions of almost periodic skew-symmetric homogeneous linear differential systems. We prove that in any neighbourhood of such a system there exists an almost periodic skew-symmetric system which does not possess any non-trivial almost ...

Existence of almost periodic solution for SICNN with a neutral delay [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this paper, a kind of shunting inhibitory cellular neural network with a neutral delay was considered. By using the Banach fixed point theorem, we established a result about the existence and uniqueness of the almost periodic solution for the shunting

Almost Periodic Solution for Forced Perturbed Non-Instantaneous Impulsive Model

open access: yesAxioms, 2022
In this paper we investigate a forced perturbed non-instantaneous impulsive model. Firstly, we prove the existence and uniqueness of an almost periodic solution for the model considered by the Banach contraction principle.

Existence of bounded solutions for retarded equations with infinite delay, impulses, and nonlocal condition

open access: yesNOVASINERGIA, 2020
In this work, we study the existence of bounded solutions for a semilinear retarded equation with infinite delay, impulse, and non-local conditions. We also show that under some conditions this bounded solution is unique, periodic, or almost periodic ...

Almost periodic processes and the existence of almost periodic solutions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 1998
The authors state an existence theorem for almost-periodic solutions to some almost-periodic evolution equations. For this, they discuss some stability notions for processes. An equivalence relation with respect to the separation condition and some stability condition are given. As example the authors study a wave equation.
