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.

Uniformly Almost Periodic Functions and Almost Periodic Solutions to Dynamic Equations on Time Scales [PDF]

open access: yesAbstract and Applied Analysis, 2011
Firstly, we propose a concept of uniformly almost periodic functions on almost periodic time scales and investigate some basic properties of them. When time scale T=ℝ or ℤ, our definition of the uniformly almost periodic functions is equivalent to the ...

Almost periodicand asymptotically almost periodic solutions of Liénard equations [PDF]

open access: yesDiscrete and Continuous Dynamical Systems - B, 2011
The aim of this paper is to study the almost periodic and asymptotically almost periodic solutions on (0,+1) of the Li´enard equation x′′ + f(x)x′ + g(x) = F(t), where F : T ! R (T = R+ or R) is an almost periodic or asymptotically almost periodic function and g : (a, b) ! R is a strictly decreasing function.

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

open access: yes, 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 ...

Structure of Fourier exponents of almost periodic functions and periodicity of almost periodic functions [PDF]

open access: yes, 1996

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

open access: yes, 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.

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

open access: yes, 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 ...
