Asymptotic properties and convolutions of some almost periodic functions with applications
AbstractIn this note we are going to continue investigation concerning the asymptotic behavior of some Levitan almost periodic functions or almost periodic functions in view of the Lebesgue measure as well as their convolutions with some functions naturally arising in the theory of ordinary linear differential equations.

Asymptotically Almost Periodic Solutions for a Class of Stochastic Functional Differential Equations [PDF]
This work is concerned with the quadratic-mean asymptotically almost periodic mild solutions for a class of stochastic functional differential equationsdxt=Atxt+Ft,xt,xtdt+H(t,xt,xt)∘dW(t). A new criterion ensuring the existence and uniqueness of the quadratic-mean asymptotically almost periodic mild solutions for the system is presented. The condition

Statistical properties of the method of regularization with periodic Gaussian reproducing kernel [PDF]
The method of regularization with the Gaussian reproducing kernel is popular in the machine learning literature and successful in many practical applications. In this paper we consider the periodic version of the Gaussian kernel regularization.

A Delay Almost Periodic Competitive System in Discrete Time
A discrete almost periodic competitive system with delay is proposed and analyzed. The system admits a unique almost periodic solution, which is shown to be uniformly asymptotically stable by using the method of Lyapunov function. Some specific numerical

Extreme phase sensitivity in systems with fractal isochrons [PDF]
Sensitivity to initial conditions is usually associated with chaotic dynamics and strange attractors. However, even systems with (quasi)periodic dynamics can exhibit it.
