3D atomic structure determination with ultrashort-pulse MeV electron diffraction [PDF]
IUCrJUnderstanding structure at the atomic scale is fundamental for understanding the functioning and the development of materials with improved properties. Compared with other probes providing atomic resolution, electrons offer the strongest interaction in ...

On Dualization over Distributive Lattices [PDF]
Discrete Mathematics & Theoretical Computer Science, 2022 Given a partially order set (poset) $P$, and a pair of families of ideals $\mathcal{I}$ and filters $\mathcal{F}$ in $P$ such that each pair $(I,F)\in \mathcal{I}\times\mathcal{F}$ has a non-empty intersection, the dualization problem over $P$ is to ...

On quasi-ideals of Γ-semihyperrings [PDF]
Journal of Hyperstructures, 2019 The concept of quasi-ideals, minimal quasi-ideals for Γsemihyperrings are introduced. Characterization of quasi-ideals and of minimal quasi-ideals of Γ-semihyperring with the help of ideals of Γ-semihyperrings have been taken into account.

The Characteristic of the Minimal Ideals and the Minimal Generalized Ideals in Rings
International Journal of Mathematics and Mathematical Sciences, 2023 In this paper, we prove that the characteristic of a minimal ideal and a minimal generalized ideal, which is meant to be one of minimal left ideal, minimal right ideal, bi-ideal, quasi-ideal, and m,n-ideal in a ring, is either zero or a prime number p ...

Generalization of f-Graphs and Their Algebraic Aspects
Journal of Mathematics, 2023 The notion of f-graphs and f-ideals are relatively new and have been studied in many papers. In this paper, we have generalized the idea of f-graphs and f-ideals to quasi f-graphs and quasi f-ideals, respectively. We have characterized all quasi f-graphs

Countable Ideals in a Semi-Lattice of the De Enumeration Degrees
Моделирование и анализ информационных систем, 2015 In the article we have proved that any countable ideal in the semi-lattice of the De is the intersection of two principal ideals generated by quasi-minimal covers for this ideal.

On quasi-prime differential semiring ideals
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2020 The notion of a \verb"quasi-prime ideal", for the first time, was introduced in differential commutative rings, i.e. commutative rings considered together with a derivation, as differential ideals maximal among those not meeting some multiplicatively ...

Dual digraphs of finite semidistributive lattices
Cubo, 2022 Dual digraphs of finite join-semidistributive lattices, meet-semidistributive lattices and semidistributive lattices are characterised. The vertices of the dual digraphs are maximal disjoint filter-ideal pairs of the lattice.
