Cyclotomic Cosets, the Mattson–Solomon Polynomial, Idempotents and Cyclic Codes [PDF]

open access: yesSignals and Communication Technology, 2017
La importante familia de códigos cíclicos binarios se explora en este capítulo. Comenzando con los cosets ciclotómicos, se introducen los polinomios mínimos. Se describe el polinomio de Mattson–Solomon y se demuestra que es una transformada de Fourier discreta inversa basada en una raíz primitiva de la unidad.

D-Optimal Designs: A Mathematical Programming Approach Using Cyclotomic Cosets [PDF]

open access: yesInformatica, 2011
In this paper, a novel approach involving the concepts from mathematical programming and number theory is proposed to find the D-optimal designs. In specific, we will propose a mathematical formulation for the D-optimal design. In addition to that, we will present the use of cyclotomic cosets in the mathematical formulation, in order to reduce the ...

Structured quasi‐cyclic low‐density parity‐check codes based on cyclotomic cosets

open access: yesIET Communications, 2015
This study considers the construction of four‐cycle free quasi‐cyclic low‐density parity‐check (QC‐LDPC) codes. These codes are based on the cyclotomic cosets of q modulo n where q is a prime power,

Quantum variations of cyclotomic cosets for cyclic stabiliser codes construction

open access: yesQuantum Information Processing
AbstractCyclotomic cosets are intrinsically linked with the design and construction of classical cyclic codes whose properties can be inferred from the coset structures. This paper proposes some new quantum variations of cyclotomic cosets for cyclic stabiliser construction.

Explicit representatives and sizes of cyclotomic cosets and their application to cyclic codes over finite fields

open access: yesFinite Fields and Their Applications
Cyclotomic coset is a classical notion in the theory of finite field which has wide applications in various computation problems. Let $q$ be a prime power, and $n$ be a positive integer coprime to $q$. In this paper we determine explicitly the representatives and the sizes of all $q$-cyclotomic cosets modulo $n$ in the general settings.

Finiteness theorems on elliptical billiards and a variant of the dynamical Mordell–Lang conjecture

open access: yesProceedings of the London Mathematical Society, Volume 127, Issue 5, Page 1268-1337, November 2023., 2023
Abstract We offer some theorems, mainly finiteness results, for certain patterns in elliptical billiards, related to periodic trajectories; these seem to be the first finiteness results in this context. For instance, if two players hit a ball at a given position and with directions forming a fixed angle in (0,π)$(0,\pi )$, there are only finitely many ...

Categorification of integral group rings extended by one dimension

open access: yesJournal of the London Mathematical Society, Volume 108, Issue 4, Page 1617-1641, October 2023., 2023
Abstract The integral group rings ZG$\mathbb {Z}G$ for finite groups G$G$ are precisely those fusion rings whose basis elements have Frobenius–Perron dimension 1, and each is categorifiable in the sense that it arises as the Grothendieck ring of a fusion category.

Quasi-Cyclic Codes Via Unfolded Cyclic Codes and Their Reversibility

open access: yesIEEE Access, 2019
The finite field $\mathbb {F}_{q^\ell }$ of $q^\ell $ elements contains $\mathbb {F}_{q}$ as a subfield. If $\theta \in \mathbb {F}_{q^\ell }$ is of degree $\ell $ over $\mathbb {F}_{q}$ , it can be used to unfold elements of $\mathbb {F}_{q^\

Some New Classes of Entanglement-Assisted Quantum MDS Codes Derived From Constacyclic Codes

open access: yesIEEE Access, 2019
Although quantum maximal-distance-separable (MDS) codes that satisfy the quantum singleton bound have become an important research topic in the quantum coding theory, it is not an easy task to search for quantum MDS codes with the minimum distance that ...

Applications of Constacyclic Codes to Some New Entanglement-Assisted Quantum MDS Codes

open access: yesIEEE Access, 2019
Generally, it is not easy to construct quantum maximal-distance-separable (MDS) codes with the minimum distance greater than $\frac {q}{2}+1$ . The minimum distance of quantum MDS codes can achieve $\frac {q}{2}+1$ or exceed $\frac {q}{2}+1$ by ...
