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 ...

On idempotent stable range 1 matrices

Special Matrices, 2022
We characterize the idempotent stable range 1, 2 × 2 matrices over commutative rings and in particular the integral matrices with this property. Several special cases and examples complete the subject.

The universal property of commutative algebras' internal crossed modules

Journal of New Results in Science, 2023
In this work, we identify subobjects and ideals in the category of internal crossed modules, which provide a deeper understanding of the structure of these objects.

Computation of eccentric topological indices of zero-divisor graphs based on their edges

AIMS Mathematics, 2022
The topological index of a graph gives its topological property that remains invariant up to graph automorphism. The topological indices which are based on the eccentricity of a chemical graph are molecular descriptors that remain constant in the whole ...

The Ideal Intersection Property for Groupoid Graded Rings [PDF]

, 2010
We show that if a groupoid graded ring has a certain nonzero ideal property, then the commutant of the center of the principal component of the ring has the ideal intersection property, that is it intersects nontrivially every nonzero ideal of the ring ...

The interpretation of commutative justice theory in the realm of contracts [PDF]

مطالعات فقه و حقوق اسلامی, 2013
Commutative justice, in the philosophy of law, means giving the exact amount of everybody’s rights and achieves without interference, and distributive justice is concerned to distribution of property by state. Commutative justice theory, from a more

Efficient Computation of Intervention in Causal Bayesian Networks [PDF]

Jisuanji kexue, 2022
In causal Bayesian networks (CBNs),it is a fundamental problem to compute the causal effect of sum product.From the perspective of a directed acyclic graph,we show every CBN has a corresponding Bayesian network.Intervention is a fundamental operation in ...

Enumeration of Involutions of Finite Rings

Journal of New Theory, 2021
In this paper, we study a special class of elements in the finite commutative rings called involutions. An involution of a ring R is an element with the property that x^2-1=0 for some x in R.

Local Uniform Convexity and Kadec-Klee Type Properties in K-interpolation spaces II

Journal of Function Spaces and Applications, 2004
We study local uniform convexity and Kadec-Klee type properties in K-interpolation spaces of Lorentz couples. We show that a wide class of Banach couples of (commutative and) non-commutative Lorentz spaces possess the (so-alled) (DGL)-property originally
