Almost periodic processes and the existence of almost periodic solutions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 1998
Some property which is equivalent to the concept of an asymptotically almost periodic integral for almost periodic processes is introduced. By using this property, it is shown that a precompact integral of almost periodic processes which is uniformly ...

Asymptotically almost periodic and almost periodic solutions for partial neutral differential equations

open access: yesApplied Mathematics Letters, 2005
This paper continues the work of the first author and \textit{H. R. Henríquez} [J. Math. Anal. Appl., 221, 452--475 (1998; Zbl 0915.35110), J. Math. Anal. Appl. 221, No.2, 499--522 (1998; Zbl 0926.35151)] for partial neutral functional-differential equations with unbounded delay, where they considered the existence of solutions and periodic solutions ...

Almost periodic generalized solutions of differential equations [PDF]

open access: yesMathematica Bohemica, 2021
The paper aims to study systems of linear ordinary differential equations in the context of an algebra of almost periodic generalized ultradistributions. Conditions on the existence of generalized solutions are given.

Investigation for periodic and almost periodic solutions of first-order ordinary differential equations [PDF]

open access: yesE3S Web of Conferences, 2023
Approaches to estimating for the number of periodic and almost periodic solutions of ordinary differential equations are considered. Conditions that allow determinating both the upper and lower bounds for these solutions are found.

Non-almost periodic solutions of limit periodic and almost periodic homogeneous linear difference systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
We study limit periodic and almost periodic homogeneous linear difference systems. The coefficient matrices of the considered systems are taken from a given commutative group.

Asymptotically almost periodic solutions of limit and almost periodic linear difference systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, limit periodic and almost periodic homogeneous linear difference systems are considered. We study the systems in which the coefficient matrices are taken from a given bounded group and the elements of the matrices are from an infinite ...
