Almost periodic Harmonizable processes

Georgian Mathematical Journal, 1996
The classical uniform almost periodic (a.p.) functions have been generalized, by omitting the continuity hypothesis, into Stepanov, Weyl and Besicovitch a.p. functions and a comprehensive account of these appears in \textit{A. S. Besicovitch}'s book [``Almost periodic functions'' (1932; Zbl 0004.25303)].

Asymptotically almost periodic, almost periodic and pseudo-almost periodic mild solutions for neutral differential equations

Nonlinear Analysis: Real World Applications, 2010
Results concerning existence and uniqueness of almost periodic, asymptotically almost periodic, and pseudo-almost periodic mild solutions are provided for the following neutral differential equation in a Banach space \(X\) \[ \frac{d}{dt}\;u(t)=Au(t) + \frac{d}{dt}\;F_1(t, u(h_1(t))) + F_2(t,u(h_2(t))), \quad t\in \mathbb{R}, \] where \(A\) is the ...

Periodicity and Almost-Periodicity

2006
Periodicity and almost-periodicity are phenomena which play an important role in most branches of mathematics and in many other sciences. This is a survey paper1 on my work in this area and on related work. I restrict myself to periodicity questions in combinatorics on words (the main dish), but I start with a periodicity problem from number theory ...

Periodic and Almost Periodic Motions

1967
By Def. 38.1 a motion described by p(t, a, t0) is called periodic with period ω if for all t ≥ t0 the relation $$ {\rm{ }}(t{\rm{ }} + {\rm{ }}\omega ,{\rm{ }}a, {t_0}){\rm{ }} = {\rm{ }}p{\rm{ }}(t,{\rm{ }}a, {t_0}) $$ (71.1) is satisfied.
