Nilpotent graphs of skew polynomial rings over non-commutative rings [PDF]
Transactions on Combinatorics, 2020 Let $R$ be a ring and $\alpha$ be a ring endomorphism of $R$. The undirected nilpotent graph of $R$, denoted by $\Gamma_N(R)$, is a graph with vertex set $Z_N(R)^*$, and two distinct vertices $x$ and $y$ are connected by an edge if and only if ...

The Eliahou-Kervaire resolution over a skew polynomial ring [PDF]
Communications in Algebra, 2021 In a 1987 paper, Eliahou and Kervaire constructed a minimal resolution of a class of monomial ideals in a polynomial ring, called stable ideals.

The Taylor Resolution Over a Skew Polynomial Ring [PDF]
Journal of Algebra and its Applications, 2021 Let $\Bbbk$ be a field and let $I$ be a monomial ideal in the polynomial ring $Q=\Bbbk[x_1,\ldots,x_n]$. In her thesis, Taylor introduced a complex which provides a finite free resolution for $Q/I$ as a $Q$-module.

Ozone Groups and Centers of Skew Polynomial Rings [PDF]
International mathematics research notices, 2023 We introduce the ozone group of a noncommutative algebra $A$, defined as the group of automorphisms of $A$, which fix every element of its center. In order to initiate the study of ozone groups, we study polynomial identity (PI) skew polynomial rings ...

Fixed points and orbits in skew polynomial rings [PDF]
Journal of Algebra and its Applications, 2022 We study orbits and fixed points of polynomials in a general skew polynomial ring $D[x,\sigma, \delta]$. We extend results of the first author and Vishkautsan on polynomial dynamics in $D[x]$.

A dual approach to structure constants for K-theory of Grassmannians [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 The problem of computing products of Schubert classes in the cohomology ring can be formulated as theproblem of expanding skew Schur polynomial into the basis of ordinary Schur polynomials. We reformulate theproblem of computing the structure constants

Irreducible skew polynomials over domains
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2021 Let S be a domain and R = S[t; σ, δ] a skew polynomial ring, where σ is an injective endomorphism of S and δ a left σ -derivation. We give criteria for skew polynomials f ∈ R of degree less or equal to four to be irreducible.

The Center of Skew Polynomial Ring over a Couple of Quaternions
Agricultural Journal, 2020 : Let, R be a ring and σ is an endomorphism for R. With multiplication rule xa = σ (a)x for all a 0 R, the set of polynomials a 0 +a 1 x+, ..., +a n x n where a i 0 R, forms a ring. The ring is called skew polynomial ring.

On skew cyclic codes over $ M_{2}(\mathbb{F}_{2}) $
AIMS Mathematics, 2023 The algebraic structure of skew cyclic codes over $ M_{2} $($ \mathbb{F}_2 $), using the $ \mathbb{F}_4 $-cyclic algebra, is studied in this work. We determine that a skew cyclic code with a polynomial of minimum degree $ d(x) $ is a free code generated ...
