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

Fractal and Fractional, 2021 This paper investigates a class of fractional-order delayed impulsive gene regulatory networks (GRNs). The proposed model is an extension of some existing integer-order GRNs using fractional derivatives of Caputo type.

Limit periodic linear difference systems with coefficient matrices from commutative groups
Electronic Journal of Qualitative Theory of Differential Equations, 2014 In this paper, limit periodic and almost periodic homogeneous linear difference systems are studied. The coefficient matrices of the considered systems belong to a given commutative group.

Almost Periodic Functions [PDF]
Proceedings of the American Mathematical Society, 1952 One of the aims in the study of almost periodic functions on a group is to generalize the Fejer summation process, whereby the Fourier series may be summed to yield the function. This has been achieved partially by Bochner-von Neumann [1] and Maak [2; 3].J But in [3] Maak says "In general it is not possible to give a summation procedure which may be ...

A generalization of Bohr's Equivalence Theorem [PDF]
, 2018 Based on a generalization of Bohr's equivalence relation for general Dirichlet series, in this paper we study the sets of values taken by certain classes of equivalent almost periodic functions in their strips of almost periodicity.

Almost Periodic Transformations [PDF]
Transactions of the American Mathematical Society, 1934 When one studies periodic transformations such as, for example, rotations, he often encounters transformations which are not periodic but which are, in a very real and non-technical sense, almost periodic. For instance, repeated rotation through an angle which is an irrational part of a revolution will never bring a point set back point-for-point into ...

Artifactual log-periodicity in finite size data: Relevance for earthquake aftershocks [PDF]
, 2000 The recently proposed discrete scale invariance and its associated log-periodicity are an elaboration of the concept of scale invariance in which the system is scale invariant only under powers of specific values of the magnification factor. We report on

Positive almost periodicity on SICNNs incorporating mixed delays and D operator
Nonlinear Analysis, 2022 This article involves a kind of shunting inhibitory cellular neural networks incorporating D operator and mixed delays. First of all, we demonstrate that, under appropriate external input conditions, some positive solutions of the addressed system exist
