On lattice of Basic Z-Ideals

open access: yesپژوهش‌های ریاضی, 2021
For an f-ring  with bounded inversion property, we show that  , the set of all basic z-ideals of , partially ordered by inclusion is a bounded distributive lattice.

Commutative Medial Near Ring

open access: yesRatio Mathematica, 2023
We deliberate a substructure of a near ring called mediality so as to create a new platform, on which many of the properties like commutativity, regular, idempotent and zero symmetric are applied with.

Response of Tree-Ring Density to Climate in Maine, U.S.A.

open access: yes, 1979
Cores of red spruce (Picea rubens Sarg.) from three upper-elevation sites in Maine, U.S.A., were X-rayed, and minimum and maximum wood densities as well as ring widths were mechanically recorded.

An extension of the reflexive property of rings

open access: yesArab Journal of Mathematical Sciences, 2019
Mason introduced the notion of reflexive property of rings as a generalization of reduced rings. For a ring endomorphism α, Krempa studied α-rigid rings as an extension of reduced rings. In this note, we introduce the notion of α-quasi reflexive rings as

Dendrochronological Modeling of the Effects of Climatic Change on Tree-Ring Width Chronologies from the Chaco Canyon Area, Southwestern United States

open access: yes, 1992
Hypotheses about the causes of the growth and decline of the Chacoan regional interaction system in the southwestern United States between A.D. 900 and 1200 are evaluated against tree-ring evidence and the results of an empirical model (PRECON) that ...

Idempotent Reflexive rings whose every simle singular right module are yj-injective [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2011
In this paper we study rightidempotent reflexive ring whose simple singular right R-module isYJ-injective, we prove that this type of ring is right weakly regular ring, we show that if R is N duo or NCI ring and R is right idempotent reflexive ring ...

Commutative rings with homomorphic power functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
A (commutative) ring R (with identity) is called m-linear (for an integer m≥2) if (a+b)m=am+bm for all a and b in R. The m-linear reduced rings are characterized, with special attention to the finite case.

On G.P.P-Rings [PDF]

open access: yesمجلة التربية والعلم, 2006
In this work we introduce the notion of G.P.P- rings and some of it is basic properties, we prove that if R is a right G.P.P- ring , then R is P.P- ring if r(an)r(a) for every aR and a positive integer n.

On the comaximal graph of a ring

open access: yesAKCE International Journal of Graphs and Combinatorics
In this paper, we prove that the study of the comaximal graph of a finite commutative ring with identity is the same as the study of the zero-divisor graph of the specially constructed lattice.
