The intersection graph of annihilator submodules of a module [PDF]
Opuscula Mathematica, 2019 Let \(R\) be a commutative ring and \(M\) be a Noetherian \(R\)-module. The intersection graph of annihilator submodules of \(M\), denoted by \(GA(M)\) is an undirected simple graph whose vertices are the classes of elements of \(Z_R(M)\setminus \text ...

An elementary approach to the homological properties of constant-rank operators
Comptes Rendus. Mathématique, 2023 We give a simple and constructive extension of Raiță’s result that every constant-rank operator possesses an exact potential and an exact annihilator.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Analysis of the Wiener Index of Rough Annihilator Graph Over Rough Semirings
Journal of MathematicsAn effective analytical and visual tool for comprehending the annihilator relationships inside a rough semiring is its annihilator graph. This paper introduces and investigates rough annihilator graph, denoted RAGT, of the commutative rough semiring T ...

Demonstratio Mathematica, 1990 The paper starts off with a characterization of the known concept of a biregular ring in terms of the complement left annihilator of a semiprime ring. A ring \(A\) is said to be a \(LIS\) ring if for any two right ideals \(I\), \(J\) of \(A\), the equality \(\ell(I\cap J)=\ell(I)+\ell(J)\) holds.

A Dislocation Perspective on Strength and Toughness in Ceramics
Advanced Engineering Materials, EarlyView.Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Relative co-annihilators in lattice equality algebras [PDF]
Mathematica BohemicaWe introduce the notion of relative co-annihilator in lattice equality algebras and investigate some important properties of it. Then, we obtain some interesting relations among $ \vee$-irreducible filters, positive implicative filters, prime filters and

The annihilator graph of a 0-distributive lattice [PDF]
Transactions on Combinatorics, 2018 In this article, for a lattice $\mathcal L$, we define and investigate the annihilator graph $\mathfrak {ag} (\mathcal L)$ of $\mathcal L$ which contains the zero-divisor graph of $\mathcal L$ as a subgraph. Also, for a 0-distributive lattice
