Linear codes and cyclic codes over finite rings and their generalizations: a survey

open access: yesElectronic Journal of Graph Theory and Applications, 2023
We survey a recent progress of cyclic codes over finite rings and their generalization to skew cyclic as well as skew cyclic codes with derivation over finite rings, focusing on structural properties of the codes.

The VIT Transform Approach to Discrete-Time Signals and Linear Time-Varying Systems

open access: yesEng, 2021
A transform approach based on a variable initial time (VIT) formulation is developed for discrete-time signals and linear time-varying discrete-time systems or digital filters.

The eigenspaces of twisted polynomials over cyclic field extensions

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
Let K be a field and σ an automorphism of K of order n. Employing a nonassociative algebra, we study the eigenspace of a bounded skew polynomial f ∈ K[t; σ].

Centrally Extended Jordan (∗)-Derivations Centralizing Symmetric or Skew Elements

open access: yesAxioms, 2023
Let A be a non-commutative prime ring with involution ∗, of characteristic ≠2(and3), with Z as the center of A and Π a mapping Π:A→A such that [Π(x),x]∈Z for all (skew) symmetric elements x∈A.

Derivations of skew polynomial rings

open access: yesPublications de l'Institut Mathematique, 2002
Let \(R\) be a commutative ring of characteristic zero, \(d_1,d_2,\dots,d_n\) commuting derivations of \(R\), and \(A_n=R[X_1,X_2,\dots,X_n;d_1,d_2,\dots,d_n]\) a skew polynomial ring in commuting variables \(X_1,X_2,\dots,X_n\) over \(R\). The authors describe derivations of \(A_n\) and examine the lattice of its ideals, under certain conditions.

On the Semisimplicity of Skew Polynomial Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1984
Let R R be a ring satisfying the maximal condition on annihilator left ideals and σ \sigma be an automorphism of R R . We show that the Jacobson radical of the skew polynomial ring R σ [ x ] {R_\sigma }[x ...

Prime Ideals and Strongly Prime Ideals of Skew Laurent Polynomial Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
We first study connections between α-compatible ideals of R and related ideals of the skew Laurent polynomials ring R[x,x−1;α], where α is an automorphism of R.

Some Notes on Semiabelian Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
It is proved that if a ring R is semiabelian, then so is the skew polynomial ring R[x;σ], where σ is an endomorphism of R satisfying σ(e)=e for all e∈E(R). Some characterizations and properties of semiabelian rings are studied.
