Coding with skew polynomial rings
The authors generalize the \(\theta\)-cyclic code defined by \textit{D. Boucher, W. Geiselmann} and \textit{F. Ulmer} [Appl. Algebra Eng. Commun. Comput. 18, No. 4, 379--389 (2007; Zbl 1159.94390)] and study their properties. These are closely related to properties of the ring \(\mathbb{F}_q[X, \theta]\) of skew polynomials [see \textit{B. R. McDonald},

ON COEFFICIENTS OF NILPOTENT POLYNOMIALS IN SKEW POLYNOMIAL RINGS [PDF]
Summary: We observe the basic structure of the products of coefficients of nilpotent (left) polynomials in skew polynomial rings. This study consists of a process to extend a well-known result for semi-Armendariz rings. We introduce the concept of \(\alpha \)-skew \(n\)-semi-Armendariz ring, where \(\alpha\) is a ring endomorphism. We prove that a ring

Prime ideals of skew polynomial rings and skew Laurent polynomial rings
Let \(S=R[X,X^{-1};\rho]\) be a skew Laurent polynomial ring over a ring \(R\) with automorphism \(\rho\). The authors characterize those prime ideals \(P\) of \(S\) with \(P\cap R=0\) in terms of irreducible polynomials over the centre of \(Q[X,X^{-1};\rho]\), where \(Q\) is the right Martindale quotient of \(R\) with respect to the filter of non-zero

Quasi-duo skew polynomial rings
A characterization of right (left) quasi-duo skew polynomial rings of endomorphism type and skew Laurent polynomial rings are given. In particular, it is shown that (1) the polynomial ring R[x] is right quasi-duo iff R[x] is commutative modulo its Jacobson radical iff R[x] is left quasi-duo, (2) the skew Laurent polynomial ring is right quasi-duo iff ...

Computation of nonlinear eigenvalues based on the Ore determinant: preliminary results [PDF]
The concept of eigenvalues has recently been generalized for nonlinear systems, but the method to find them is missing. Unlike the linear case, now one has to deal with non-commutative polynomials from the Ore ring. In the paper, the Ore determinant of a

Semifields from skew polynomial rings [PDF]
Abstract Skew polynomial rings are used to construct finite semifields, following from a construction of Ore and Jacobson of associative division algebras. Johnson and Jha [10] constructed the so-called cyclic semifields, obtained using irreducible semilinear transformations.

Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Uniserial Rings and Skew Polynomial Rings
If \(\tau\) is an automorphism of a division ring D then, for each positive integer c, the factor ring \(S/x^ cS\) of the skew polynomial ring \(S=D[x;\tau]\) is a local uniserial ring of split type. The purpose of this paper is to establish a necessary and sufficient condition on a local uniserial ring R for R to be isomorphic to a ring of the above ...
