Hearts for commutative Noetherian rings: torsion pairs and derived equivalences

open access: yesDocumenta Mathematica, 2021
Over a commutative noetherian ring R , the prime spectrum controls, via the assignment of support, the structure of both \mathsf{Mod}(R) and

Characterizations of derivations [PDF]

open access: yes, 2019
The main purpose of this work is to characterize derivations through functional equations. This work consists of five chapters. In the first one, we summarize the most important notions and results from the theory of functional equations. In Chapter 2 we

Semigroup ideal in Prime Near-Rings with Derivations

open access: yesمجلة بغداد للعلوم, 2011
In this paper we generalize some of the results due to Bell and Mason on a near-ring N admitting a derivation D , and we will show that the body of evidence on prime near-rings with derivations have the behavior of the ring.

On derivations and commutativity in prime rings [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
Let R be a prime ring of characteristic different from 2, d a nonzero derivation of R, and I a nonzero right ideal of R such that [[d(x), x], [d(y), y]] = 0, for all x, y ∈ I. We prove that if [I, I]I ≠ 0, then d(I)I = 0.

Prime gamma rings with centralizing and commuting generalized derivations [PDF]

open access: yesInternational Journal of Algebra, 2013
Let $M$ be a prime $ $-ring satisfying a certain assumption and $D$ a nonzero derivation on $M$. Let $f:M\rightarrow M$ be a generalized derivation such that $f$ is centralizing and commuting on a left ideal $J$ of $M$. Then we prove that $M$ is commutative.

On rigid derivations in rings

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2014
We prove that in a ring $R$ with an identity there exists an element $a\in R$ and a nonzero derivation $d\in Der R$ such that $ad(a)\neq 0$. A ring $R$ is said to be a $d$-rigid ring for some derivation $d \in Der R$ if  $d(a)=0$ or $ad(a)\neq 0$ for all

On Hasse--Schmidt derivations: the action of substitution maps [PDF]

open access: yes, 2018
We study the action of substitution maps between power series rings as an additional algebraic structure on the groups of Hasse--Schmidt derivations. This structure appears as a counterpart of the module structure on classical derivations.Comment: 42 ...

Commutativity of rings and near-rings with generalized derivations

open access: yesIndian Journal of Pure and Applied Mathematics, 2013
Let \(N\) be a 3-prime near-ring, and let \(f\) and \(g\) be nonzero generalized derivations on \(N\). Let \(V\) be a nonzero semigroup ideal of \(N\) -- i.e. a subset such that \(VN\subseteq V\) and \(NV\subseteq V\); and let \(U\) be a nonempty subset of \(N\). The authors explore the commutativity results which follow from the following hypotheses: (

Identities with derivations and automorphisms on semiprime rings

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
The purpose of this paper is to investigate identities with derivations and automorphisms on semiprime rings. A classical result of Posner states that the existence of a nonzero centralizing derivation on a prime ring forces the ring to be commutative ...

Derivation of Commutative Rings and the Leibniz Formula for Power of Derivation [PDF]

open access: yesFormalized Mathematics, 2021
Summary In this article we formalize in Mizar [1], [2] a derivation of commutative rings, its definition and some properties. The details are to be referred to [5], [7]. A derivation of a ring, say D, is defined generally as a map from a commutative ring A to A-Module M with specific conditions. However we start with simpler case, namely
