Almost Periodic Time Scales and Almost Periodic Functions on Time Scales [PDF]

Journal of Applied Mathematics, 2015
We propose some new concepts of almost periodic time scales and almost periodic functions on time scales and give some basic properties of these new types of almost periodic time scales and almost periodic functions on time scales.

Almost periodic generalized solutions of differential equations [PDF]

Mathematica 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.

Almost periodic skew-symmetric differential systems [PDF]

Electronic 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 ...

Almost periodic solutions of neutral functional differential equations with Stepanov-almost periodic terms

Electronic Journal of Differential Equations, 2011
In this paper we study the existence of almost periodic solutions of an autonomous neutral functional differential equation with Stepanov-almost periodic terms in a Banach space.

Further properties of Stepanov--Orlicz almost periodic functions [PDF]

, 2020
summary:We revisit the concept of Stepanov--Orlicz almost periodic functions introduced by Hillmann in terms of Bochner transform. Some structural properties of these functions are investigated.

Vector-valued pseudo almost periodic functions [PDF]

, 1997
summary:Vector-valued pseudo almost periodic functions are defined and their properties are investigated. The vector-valued functions contain many known functions as special cases.

Remotely $c$-almost periodic type functions in ${\mathbb{R}}^{n}$

, 2022
summary:In this paper, we relate the notions of remote almost periodicity and quasi-asymptotical almost periodicity; in actual fact, we observe that a remotely almost periodic function is nothing else but a bounded, uniformly continuous quasi ...

Stability of unique pseudo almost periodic solutions with measure [PDF]

, 2020
summary:By means of the fixed-point methods and the properties of the $\mu $-pseudo almost periodic functions, we prove the existence, uniqueness, and exponential stability of the $\mu $-pseudo almost periodic solutions for some models of recurrent ...
