Q-factorial Laurent rings

open access: yes, 2011
Dolgachev proved that, for any field k, the ring naturally associated to a generic Laurent polynomial in d variables, $d \geq 4$, is factorial. We prove a sufficient condition for the ring associated to a very general complex Laurent polynomial in d=3 ...

Lower Bounds on Solutions of Quadratic Polynomials Defined over Finite Rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
Let m be a positive integer and let Rm denote the ring Z/(m), and let Rmn denote the Cartesian product of n copies of Z/m. Let f(x) be a quadratic polynomial in Z[x1,…,xn].

A note on rings which are multiplicatively generated by idempotents and nilpotents

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
We give the structure of certain rings which are multiplicatively generated by nilpotents or multiplicatively generated by idempotents and nilpotents.

Polynomial Functors of Modules [PDF]

open access: yes, 2014
We introduce the notion of numerical functors to generalise Eilenberg & MacLane's polynomial functors to modules over a binomial base ring. After shewing how these functors are encoded by modules over a certain ring, we record a precise criterion for a ...

A Matrix Ring Description for Cyclic Convolutional Codes

open access: yes, 2007
In this paper, we study convolutional codes with a specific cyclic structure. By definition, these codes are left ideals in a certain skew polynomial ring.

On ideals with the Rees property

open access: yes, 2013
A homogeneous ideal $I$ of a polynomial ring $S$ is said to have the Rees property if, for any homogeneous ideal $J \subset S $ which contains $I$, the number of generators of $J$ is smaller than or equal to that of $I$. A homogeneous ideal $I \subset S$

M-Polynomial and Topological Indices of Benzene Ring Embedded in P-Type Surface Network

open access: yesJournal of Chemistry, 2019
The representation of chemical compounds and chemical networks with the M-polynomials is a new idea, and it gives nice and good results of the topological indices.

Improved Ring LWR-Based Key Encapsulation Mechanism Using Cyclotomic Trinomials

open access: yesIEEE Access, 2020
In the field of post-quantum cryptography, lattice-based cryptography has received the most noticeable attention. Most lattice-based cryptographic schemes are constructed based on the polynomial ring Rq = Zq[x]/f (x), using a cyclotomic polynomial f (x).

Coherence of polynomial rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
The main result is that A [ X ] A[X] , the polynomial ring in any number of indeterminates over a coherent ring A A of global dimension two, is coherent.

Skew Polynomial Rings

open access: yesIndagationes Mathematicae (Proceedings), 1968
ABSTRACTSkew polynomial rings .are considered with a multiplication defined byx•a=a1x+a1x2+…+arxr,ai∈K,where K is a (skew) field and the ai depend on a ∈ K. Under certain conditions the rings appear to be non-commutative principal ideal rings with a unique factorization.
