Some results on the annihilator graph of a commutative ring [PDF]
, 2017 summary:Let $R$ be a commutative ring. The annihilator graph of $R$, denoted by ${\rm AG}(R)$, is the undirected graph with all nonzero zero-divisors of $R$ as vertex set, and two distinct vertices $x$ and $y$ are adjacent if and only if ${\rm ann}_R(xy)

Weighted veronese rings via convex semigroups
Bulletin of the London Mathematical Society, Volume 58, Issue 11, November 2026.Abstract We determine several properties of two‐dimensional normal affine semigroup rings, and in particular of weighted Veronese rings, including determinantal presentations, Gröbner bases, graded Hilbert series and graded Betti numbers, the structure of their associated graded rings, and their Koszul property.

On matrix Lie rings over a commutative ring that contain the special linear Lie ring [PDF]
, 2016 summary:Let $K$ be an associative and commutative ring with $1$, $k$ a subring of $K$ such that $1\in k$, $n\geq 2$ an integer. The paper describes subrings of the general linear Lie ring $gl_{n} ( K )$ that contain the Lie ring of all traceless matrices

Geographical Analysis, Volume 58, Issue 4, October 2026.ABSTRACT Scale is central to inference in natural and social systems, and geography and ecology have treated it as an explicit object of theory for decades. This paper builds on that work with a formal view in which scale is a degree of freedom of description, parameterizing both the mappings between representations and the metric defining distance and

The Zero-Divisor Graph of a Commutative Ring
, 1999 For each commutative ring R we associate a (simple) graph Γ(R). We investigate the interplay between the ring-theoretic properties of R and the graph-theoretic properties of Γ(R)

A note on co-maximal graphs of commutative rings
AKCE International Journal of Graphs and Combinatorics, 2018 Let R be a commutative ring with unity. The co-maximal graph Γ ( R ) is the graph with vertex set R and two vertices a and b are adjacent if R a + R b = R .

Rethinking Merit in Calvin's Doctrine of the Atonement: Beyond Possessive Individualism
International Journal of Systematic Theology, Volume 28, Issue 4, Page 378-400, October 2026.Abstract Joan Lockwood O'Donovan argues that the Reformation doctrine of grace entails a rejection of the proprietary anthropology of self‐owning individuals and its attendant notion of justice – what C. B. Macpherson termed the “theory of possessive individualism.” Although O'Donovan praises Calvin's anthropology and his account of law for its non ...
