Almost Periodicity in Chaos [PDF]

, 2018
Periodicity plays a significant role in the chaos theory from the beginning since the skeleton of chaos can consist of infinitely many unstable periodic motions.

Existence of $S^2$-almost periodic solutions to a class of nonautonomous stochastic evolution equations

Electronic Journal of Qualitative Theory of Differential Equations, 2008
The paper studies the notion of Stepanov almost periodicity (or $S^2$-almost periodicity) for stochastic processes, which is weaker than the notion of quadratic-mean almost periodicity.

Stepanov-like pseudo almost periodic functions on time scales and applications to dynamic equations with delay

Open Mathematics, 2018
In this paper, we introduce the concept of Sp-pseudo almost periodicity on time scales and present some basic properties of it, including the translation invariance, uniqueness of decomposition, completeness and composition theorem.
