Almost periodic functions, constructively [PDF]

open access: yesLogical Methods in Computer Science, 2005
The almost periodic functions form a natural example of a non-separable normed space. As such, it has been a challenge for constructive mathematicians to find a natural treatment of them.

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

open access: yesJournal 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.

Computing with almost periodic functions [PDF]

open access: yesActa Crystallographica Section A: Foundations and Advances, 2008
The paper develops a method for discrete computational Fourier analysis of functions defined on quasicrystals and other almost periodic sets. A key point is to build the analysis around the emerging theory of quasicrystals and diffraction in the setting on local hulls and dynamical systems.

Composition Theorems of Stepanov Almost Periodic Functions and Stepanov-Like Pseudo-Almost Periodic Functions

open access: yesAdvances in Difference Equations, 2011
We establish a composition theorem of Stepanov almost periodic functions, and, with its help, a composition theorem of Stepanov-like pseudo almost periodic functions is obtained.

On Hartman almost periodic functions [PDF]

open access: yesStudia Mathematica, 2006
We consider multi-dimensional Hartman almost periodic functions and sequences, defined with respect to different averaging sequences of subsets in Rd or Zd. We consider the behavior of their Fourier-Bohr coefficients and their spectrum, depending on the particular averaging sequence, and we demonstrate this dependence by several examples. Extensions to

Almost periodic functions on Hausdorff almost periodic time scales

open access: yesAdvances in Difference Equations, 2017
This paper is devoted to generalizing the notion of almost periodic functions on time scales. We introduce a new class of almost periodic time scales called Hausdorff almost periodic time scales by using the Hausdorff distance and propose a more general ...
