Weyl almost periodic functions on time scales and their Fourier series

Demonstratio Mathematica
In this paper, firstly, we propose a concept of Weyl almost periodic functions on time scales by trigonometric polynomial approximation, and study some basic properties of Weyl almost periodic functions on time scales.

© Hindawi Publishing Corp. ON SOME CLASSES OF ALMOST PERIODIC FUNCTIONS IN ABSTRACT SPACES

, 2004
We deal with C (n)-almost periodic functions taking values in a Banach space. We give several properties of such functions, in particular, we investigate their behavior in view of differentiation as well as integration.

Structure Of Fourier Exponents Of Almost Periodic Functions And Periodicity Of Almost Periodic Functions

, 2007
. The paper deals with almost periodic functions which are limits of sequences of continuous periodic functions, and determines the structure of their Fourier exponents and their ranges. It is shown that the class CP (X ) of continuous periodic functions
