Realization of an ideal Weyl semimetal band in a quantum gas with 3D spin-orbit coupling
Science, 2021 A minimal Weyl semimetal Many compounds have now been identified as Weyl semimetals, materials with an unusual electronic band structure characterized by the so-called Weyl points. Weyl points always appear in pairs, but the solid-state materials studied

On bi-ideals of Γ-semihyperrings [PDF]
Journal of Hyperstructures, 2023 The concept of Γ-semihyperrings is a generalization of semirings, semihyperrings and Γ-semirings. The notion of bi-ideals and minimal bi-ideals in Γ-semihyperrings is introduced with several examples.

Minimal generators for symmetric ideals [PDF]
Proceedings of the American Mathematical Society, 2008 Let $K$ be a field, and let $R = K[X]$ be the polynomial ring in an infinite collection $X$ of indeterminates over $K$. Let ${\mathfrak S}_{X}$ be the symmetric group of $X$. The group ${\mathfrak S}_{X}$ acts naturally on $R$, and this in turn gives $R$ the structure of a left module over the (left) group ring $R[{\mathfrak S}_{X}]$.

On minimal ideals in pseudo-finite semigroups [PDF]
Canadian Journal of Mathematics - Journal Canadien de Mathematiques, 2022 A semigroup S is said to be right pseudo-finite if the universal right congruence can be generated by a finite set $U\subseteq S\times S$ , and there is a bound on the length of derivations for an arbitrary pair $(s,t)\in S\times S$ as a consequence ...

Ideal algorithms in healthcare: Explainable, dynamic, precise, autonomous, fair, and reproducible
PLOS Digital Health, 2022 Established guidelines describe minimum requirements for reporting algorithms in healthcare; it is equally important to objectify the characteristics of ideal algorithms that confer maximum potential benefits to patients, clinicians, and investigators ...

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.

Minimal Systems of Binomial Generators for the Ideals of Certain Monomial Curves
Mathematics, 2021 Let a,b and n>1 be three positive integers such that a and ∑j=0n−1bj are relatively prime. In this paper, we prove that the toric ideal I associated to the submonoid of N generated by {∑j=0n−1bj}∪{∑j=0n−1bj+a∑j=0i−2bj∣i=2,…,n} is determinantal. Moreover,

A MINIMAL SET OF GENERATORS FOR THE CANONICAL IDEAL OF A NONDEGENERATE CURVE [PDF]
Journal of the Australian Mathematical Society, 2014 We give an explicit way of writing down a minimal set of generators for the canonical ideal of a nondegenerate curve, or of a more general smooth projective curve in a toric surface, in terms of its defining Laurent polynomial.

Isotropic porous structure design methods based on triply periodic minimal surfaces
, 2021 Recently, triply periodic minimal surface (TPMS) is emerging as an ideal tool to generate porous structures. Yet, most of the current work only focuses on controlling the elastic modulus by the relative density. For special engineering applications, such

On orderedΓ-hypersemigroups, minimal bi-ideals, and minimal left ideals
TURKISH JOURNAL OF MATHEMATICS, 2021 A \(\Gamma\)-hypersemigroup is defined as a non-empty set \(S\) with a set \(\Gamma\) of hyperoperations of \(S\), such that for \(x,y,z\in S\) and \(\alpha,\beta\in \Gamma\), \(x\alpha(y\beta z)=(x\alpha y)\beta z\). \textit{Y. Cao} and \textit{X. Xu} showed in [Semigroup Forum 60, No.
