Limit operators, collective compactness, and the spectral theory of infinite matrices [PDF]

open access: yes, 2010
In the first half of this memoir we explore the interrelationships between the abstract theory of limit operators (see e.g. the recent monographs of Rabinovich, Roch and Silbermann (2004) and Lindner (2006)) and the concepts and results of the ...

Almost Periodic Sequence Solutions of a Discrete Predator-Prey System with Beddington-DeAngelis Functional Response

open access: yesAbstract and Applied Analysis, 2014
This paper considers a discrete predator-prey system with Beddington-DeAngelis functional response. Sufficient conditions are obtained for the existence of the almost periodic solution which is uniformly asymptotically stable by constructing a Lyapunov ...

Feature-Extraction-Based Iterated Algorithms to Solve the Unrelated Parallel Machine Problem With Periodic Maintenance Activities

open access: yesIEEE Access, 2021
This paper considers an unrelated parallel machine problem with job release times and maintenance activities, in which machines have to periodically undergo maintenance since the status of the machines will be deteriorated by job-induced dirt.

Forbidden Substrings, Kolmogorov Complexity and Almost Periodic Sequences [PDF]

open access: yes, 2006
Assume that for some $ <1$ and for all nutural $n$ a set $F_n$ of at most $2^{ n}$ "forbidden" binary strings of length $n$ is fixed. Then there exists an infinite binary sequence $ $ that does not have (long) forbidden substrings. We prove this combinatorial statement by translating it into a statement about Kolmogorov complexity and compare ...

Quasiperiodic Dielectric Gratings for Multiband Fiber-To-Chip Couplers

open access: yesIEEE Photonics Journal, 2020
Dielectric gratings that couple optical fibers and planar waveguide circuits are key for optical-to-electronic (electronic-to-optical) signal conversion, but their applicability to platforms that require broader bandwidths and higher capacity is limited ...

Strong approximation of lacunary series with random gaps [PDF]

open access: yes, 2017
We investigate the asymptotic behavior of sums (Formula presented.), where f is a mean zero, smooth periodic function on (Formula presented.) and (Formula presented.) is a random sequence such that the gaps (Formula presented.) are i.i.d.

Maximally Almost Periodic Groups and Respecting Properties [PDF]

open access: yesDescriptive Topology and Functional Analysis II, 2017
For a Tychonoff space $X$, denote by $\mathfrak{P}$ the family of topological properties $\mathcal{P}$ of being a convergent sequence or being a compact, sequentially compact, countably compact, pseudocompact and functionally bounded subset of $X ...

Rationally almost periodic sequences, polynomial multiple recurrence and symbolic dynamics [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2018
A set$R\subset \mathbb{N}$is calledrationalif it is well approximable by finite unions of arithmetic progressions, meaning that for every$\unicode[STIX]{x1D716}>0$there exists a set$B=\bigcup _{i=1}^{r}a_{i}\mathbb{N}+b_{i}$, where$a_{1},\ldots ,a_{r},b_{1},\ldots ,b_{r}\in \mathbb{N}$, such that$$\begin{eqnarray}\overline{d}(R\triangle B):=\limsup ...

Phase diagram and complex patterns in the modeling of the bromate-oxalic acid-Ce-acetone oscillating reaction

open access: yesQuímica Nova, 2007
Simulations have been carried out on the bromate - oxalic acid - Ce(IV) - acetone oscillating reaction, under flow conditions, using Field and Boyd's model (J. Phys. Chem. 1985, 89, 3707).
