Polynomial Rings over Pseudovaluation Rings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Let R be a ring. Let σ be an automorphism of R. We define a σ-divided ring and prove the following. (1) Let R be a commutative pseudovaluation ring such that x∉P for any P∈Spec(R[x,σ]) . Then R[x,σ] is also a pseudovaluation ring.

Generalized Weyl algebras and diskew polynomial rings [PDF]

open access: yesJournal of Algebra and its Applications, 2020
The aim of the paper is to extend the class of generalized Weyl algebras (GWAs) to a larger class of rings (they are also called GWAs) that are determined by two ring endomorphisms rather than one as in the case of ‘old’ GWAs.

Differential polynomial rings over rings satisfying a polynomial identity [PDF]

open access: yesJournal of Algebra, 2014
Let R be a ring satisfying a polynomial identity and let δ be a derivation of R. We show that if R is locally nilpotent then R[x;δ] is locally nilpotent. This affirmatively answers a question of Smoktunowicz and Ziembowski.

Polynomial identity rings as rings of functions

open access: yesJournal of Algebra, 2007
We generalize the usual relationship between irreducible Zariski closed subsets of the affine space, their defining ideals, coordinate rings, and function fields, to a non-commutative setting, where “varieties” carry a PGLn-action, regular and rational ...

Algorithmic Properties of Polynomial Rings

open access: yesJournal of Symbolic Computation, 1998
In this paper we investigate how algorithms for computing heights, radicals, unmixed and primary decompositions of ideals can be lifted from a Noetherian commutative ringRto polynomial rings ...

On the Waring problem for polynomial rings. [PDF]

open access: yesProc Natl Acad Sci U S A, 2012
In this note we discuss an analog of the classical Waring problem for . Namely, we show that a general homogeneous polynomial of degree divisible by k ≥2 can be represented as a sum of at most k

Ring-LWE in Polynomial Rings [PDF]

open access: yesIACR Cryptology ePrint Archive, 2012
The Ring-LWE problem, introduced by Lyubashevsky, Peikert, and Regev (Eurocrypt 2010), has been steadily finding many uses in numerous cryptographic applications. Still, the Ring-LWE problem defined in [LPR10] involves the fractional ideal R ∨, the dual of the ring R , which is the source of many theoretical and implementation technicalities. Until now,

Nilpotent graphs of skew polynomial rings over non-commutative rings [PDF]

open access: yesTransactions 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 ...
