An hypervaluation of a ring onto a totally ordered non-cancellative semigroup without zero divisors
International Journal of Mathematics and Mathematical Sciences, 1986 In this paper we answer to a question posed by Marc KRANSER: It is possible to have a totally ordered noncancellative semigroup without zero divisors, and a ring hypervaluated by this semigroup?

On the automorphisms of the power semigroups of a numerical semigroup
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract If H$H$ is a numerical semigroup (i.e., a cofinite subset of the non‐negative integers closed under addition), then the collection of all non‐empty subsets of H$H$ forms a semigroup P(H)$\mathcal {P}(H)$ under the sumset operation induced by addition in H$H$.

Some results on ordered filters of implicative semigroups
International Journal of Mathematics and Mathematical Sciences, 2001 We introduce a special set in an implicative semigroup. Using it, an equivalent condition of an ordered filter is stated. We prove that an ordered filter can be represented by the union of such sets.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

From ordered semigroups to ordered $\Gamma$-hypersemigroups
Turkish Journal of Mathematics, 2022 Summary: In an attempt to show the way we pass from ordered semigroups to ordered \(\Gamma\)-hypersemigroups, we examine our results [Semigroup Forum 44, No. 3, 341--346 (1992; Zbl 0756.06008)] for an ordered \(\Gamma\)-hypersemigroup. It has been shown that the concept of semisimple ordered \(\Gamma\)-hypersemigroup \(S\) is identical with the concept

Union soft set theory applied to ordered semigroups
International Journal of Analysis and Applications, 2020 The uni-soft type of bi-ideals in ordered semigroup is considered. The notion of a uni-soft bi-ideal is introduced and the related properties are investigated.

On f - prime radical in ordered semigroups
Open Mathematics, 2018 In this paper, we introduce the concepts of f-prime ideals, f-semiprime ideals and f-prime radicals in ordered semigroups. Furthermore, some results on f-prime radicals and f-primary decomposition of an ideal in an ordered semigroup are obtained.

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3018-3037, June 2026.Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Constructive counterparts of some interior ideals in a co-quasiordered semigroup
European Journal of Mathematics and Applications, 2023 In this paper, as a further generalization of co-ideals in semigroup with apartness ordered under a co-quasiorder relation, we introduce the notions of interior co-ideals, quasi-interior co-ideals and weak-interior co-ideals.

Long‐Time Solvability and Asymptotics for the 3D Rotating MHD Equations
Mathematische Nachrichten, Volume 299, Issue 6, Page 1480-1509, June 2026.ABSTRACT We consider the initial value problem for the 3D incompressible rotating MHD equations around a constant magnetic field. We prove the long‐time existence and uniqueness of solutions for small viscosity coefficient and high rotating speed. Moreover, we investigate the asymptotic behavior of solutions in the limit of vanishing viscosity and fast
