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 ...

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=

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.

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 ...

Management coverage and spatial gaps for carnivore habitat across Mexico

Conservation Science and Practice, Volume 8, Issue 9, September 2026.
We evaluated the spatial overlap between four land management types and the habitat of 28 terrestrial carnivores in Mexico. Our findings reveal that non‐designated land management types like Indigenous Territories may provide significant habitat coverage, and that significant coverage gaps for carnivores remain.

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 ...

NEW DATA ON THE SERTORIAN WAR AT THE VASCON SITE OF IRULEGI (ARANGUREN VALLEY, NAVARRE)

Oxford Journal of Archaeology, Volume 45, Issue 2, Page 180-203, May 2026.
Summary Literary sources provide limited information on specific developments during the civil wars of the late Roman Republic, including the Sertorian War. This study describes the attack on the Vascon settlement of Irulegi (Aranguren valley, Navarre), in northern Spain, within the context of this conflict, using the methodological and theoretical ...

Alpha - Skew Pi - Armendariz Rings

, 2018
In this article we introduce a new concept called Alpha-skew Pi-Armendariz rings (Alpha - S Pi - AR)as a generalization of the notion of Alpha-skew Armendariz rings.Another important goal behind studying this class of rings is to employ it in order to ...
