Properties of Armendariz rings and weak Armendariz rings

Publications de l'Institut Mathematique, 2009
We consider some properties of Armendariz and rigid rings. We prove that the direct product of rigid (weak rigid), weak Armendariz rings is a rigid (weak rigid), weak Armendariz ring. On the assumption that the factor ring R/I is weak Armendariz, where I is nilpotent ideal, we prove that R is a weak Armendariz ring.

ON SKEW GENERALIZED TRIANGULAR MATRIX RINGS [PDF]

Journal of Algebraic Systems
In this article, we study skew monoid rings in which the monoid used in their structure is a quotient of a free monoid. We study annihilator conditions of them and describe conditions for transferring some properties from the base ring $R$ to these ...

A PROOF ON POWER-ARMENDARIZ RINGS

Korean Journal of Mathematics, 2013
Summary: Power-Armendariz is a unifying concept of Armendariz and commutative. Let \(R\) be a ring and \(I\) be a proper ideal of \(R\) such that \(R/I\) is a power-Armendariz ring. Han et al. proved that if \(I\) is a reduced ring without identity then \(R\) is power-Armendariz.

α-Skew π-McCoy Rings

Journal of Applied Mathematics, 2013
As a generalization of α-skew McCoy rings, we introduce the concept of α-skew π-McCoy rings, and we study the relationships with another two new generalizations, α-skew π1-McCoy rings and α-skew π2-McCoy rings, observing the relations with α-skew McCoy ...

On Nil-Symmetric Rings

Journal of Mathematics, 2014
The concept of nil-symmetric rings has been introduced as a generalization of symmetric rings and a particular case of nil-semicommutative rings. A ring R is called right (left) nil-symmetric if, for a,b,c∈R, where a,b are nilpotent elements, abc=0  (cab=

On partial skew Armendariz rings [PDF]

, 2011
In this paper we consider rings R with a partial action α of an infinite cyclic group G on R. We introduce the concept of partial skew Armendariz rings and partial α-rigid rings. We show that partial α-rigid rings are partial skew Armendariz rings and

A GENERALIZATION OF NIL-ARMENDARIZ RINGS

Journal of Algebra and Its Applications, 2013
Let R be a ring, M a monoid and ω : M → End (R) a monoid homomorphism. The skew monoid ring R * M is a common generalization of polynomial rings, skew polynomial rings, (skew) Laurent polynomial rings and monoid rings. In the current work, we study the nil skew M-Armendariz condition on R, a generalization of the standard nil-Armendariz condition from

Globalization, internal migration, and public goods provision in emerging economies

American Journal of Political Science, EarlyView.
Abstract Globalization can introduce new employment opportunities to emerging economies in multinational corporations and exporting firms. Who is best positioned to benefit, and what are the political consequences for “left behind” areas? We argue that primarily advantaged groups seize these opportunities through internal migration toward centers of ...

Leveraging the TabPFN Algorithm for High‐Resolution Mapping of Groundwater Bicarbonate and Its Scaling Risk Across China

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Large‐scale groundwater quality prediction is often constrained by sparse sampling, limiting the reliability of spatial assessments. This study introduces Tabular Prior‐data Fitted Network (TabPFN), a machine learning model based on prior‐fitting networks, to address this challenge and enable high‐precision mapping of groundwater bicarbonate ...
