WEAKLY ALMOST PERIODICITY AND DISTRIBUTIONAL CHAOS IN A SEQUENCE

International Journal of Modern Physics B, 2007
Let (∑, ρ) be a one-sided symbolic space (with two symbols) and σ be the shift on ∑. Denote the set of almost periodic points by A(·) and the set of weakly almost periodic points by W(·). In this paper, we prove that there exists an uncountable set J such that σ|J is distributively chaotic in a sequence, and J⊂W(σ)-A(σ).

Stabilization of Almost Periodic Piecewise Linear Systems with Norm-Bounded Uncertainty for Roll-to-Roll Dry Transfer Manufacturing Processes

American Control Conference
This paper presents the first stabilization result for almost periodic piecewise linear systems (APPLSs) with both norm-bounded additive modeling uncertainty and dwell-time uncertainty. The technique employs a mixed-mode time-varying Lyapunov function to

ON THE STABILITY OF THE “INFECTION-FREE” ALMOST PERIODIC SOLUTION IN AN IMPULSIVE SIR MODEL

Journal of Mathematics Mechanics and Computer Science
The paper investigates the stability of an infection-free almost periodic solution of an impulsive SIR model describing the spread of infection in biological systems or vulnerability to malicious software in computer networks.

Uniform Exponential Stability of Discrete Semigroup and Space of Asymptotically Almost Periodic Sequences

Zeitschrift für Analysis und ihre Anwendungen, 2015
We prove that the discrete semigroup \mathbb{T}= \{\mathcal{T}(n): n \in \mathbb{Z_+}\} is uniformly exponentially stable if and only if for each z(n)\in \mathbb{AAP}_0(\mathbb{Z}_+,\mathcal{X})

Almost Six-Phase Sequences with Perfect Periodic Autocorrelation Function

2014
A new family of almost six-phase sequences with perfect periodic autocorrelation function is obtained. The distinctive features of these sequences are: fairly frequent grid of periods, quasi-perfect periodic cross-correlation function, and nearly unit peak-factor.

Averaging sequences and modulated ergodic theorems for weakly almost periodic group representations

Journal d'Analyse Mathématique, 1999
Let \(T\) be a weakly almost periodic (WAP) representation of a locally compact \(\sigma\)-compact group \(G\) by linear operators in a Banach space \(X\). Let \(Mx\) be the unique fixed point in the closed convex hull of the orbit of \(x\) under \(T\). A sequence \(\{\mu_n\}\) of probabilities is said to average \(T\) [weakly] if \(\int T(t)x\mu_n(dt)\

Almost split sequences for TrD-periodic modules

1980
In this paper we associate to each TrD-periodic module, over an artin algebra, a diagram and show that the diagram is one of the Dynkin diagrams or one of the Open image in new ...
