Acyclic Complexes and Graded Algebras

Mathematics, 2023
We already know that the noncommutative N-graded Noetherian algebras resemble commutative local Noetherian rings in many respects. We also know that commutative rings have the important property that every minimal acyclic complex of finitely generated ...

Establishing Shape Correspondences: A Survey

Computer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

LINKAGE AND DUALITY OF MODULES

, 2009
Martsinkovsky and Strooker [13] recently introduced module theoretic linkage using syzygy and transpose. This generalization brings possibility of much application of linkage, especially, to homological theory of modules. In the present paper, we connect

Z-Polynomials and Ring Commutativity [PDF]

Mathematical Proceedings of the Royal Irish Academy, 2012
We characterise polynomials f with integer coefficients such that a ring with unity R is necessarily commutative if f(x) is central for all x Ɛ R. We also solve the corresponding problem without the assumption that the ring has a unity.

Rethinking Merit in Calvin's Doctrine of the Atonement: Beyond Possessive Individualism

International Journal of Systematic Theology, EarlyView.
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 ...

A commutativity‐or‐finiteness condition for rings [PDF]

International Journal of Mathematics and Mathematical Sciences, 2004
We show that a ring with only finitely many noncentral subrings must be either commutative or finite.

Aggregation and the Structure of Value

Noûs, EarlyView.
ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

On Prime Rings with Derivations

Axioms
This paper identifies all derivations associated with two well-known non-commutative prime rings and provides some remarks on one of these derivations, called the prime derivation.
