Arithmetic of commutative semigroups with a focus on semigroups of ideals and modules [PDF]
, 2016 Let $H$ be a commutative semigroup with unit element such that every non-unit can be written as a finite product of irreducible elements (atoms). For every $k \in \mathbb N$, let $\mathscr U_k (H)$ denote the set of all $\ell \in \mathbb N$ with the ...

Additively irreducible sequences in commutative semigroups [PDF]
Journal of Combinatorial Theory, 2015 Let $\mathcal{S}$ be a commutative semigroup, and let $T$ be a sequence of terms from the semigroup $\mathcal{S}$. We call $T$ an (additively) {\sl irreducible} sequence provided that no sum of its some terms vanishes.

On absorption in semigroups and $n$-ary semigroups [PDF]
Logical Methods in Computer Science, 2015 The notion of absorption was developed a few years ago by Barto and Kozik and immediately found many applications, particularly in topics related to the constraint satisfaction problem.

Produk Cartesius Semipgrup Smarandache
Jurnal Matematika, 2012 Smarandache semigroups is an expansion of semigroup structure, by taking a proper subset of semigroups which is in form of group. But, a proper subset which is in form of group cannot always be found in semigroups.

Asymptotic ω-Primality of Finitely Generated Cancelative Commutative Monoids
Mathematics, 2023 The computation of ω-primality has been object of study, mainly, for numerical semigroups due to its multiple applications to the Factorization Theory. However, its asymptotic version is less well known.

Morita invariants for partially ordered semigroups with local units; pp. 38–47 [PDF]
Proceedings of the Estonian Academy of Sciences, 2012 We study Morita invariants for strongly Morita equivalent partially ordered semigroups with several types of local units. These include the greatest commutative images, satisfying a given inequality and the fact that strong Morita equivalence preserves ...

Abelization of join spaces of affine transformations of ordered field with proximity
Applied General Topology, 2005 Using groups of affine transformations of linearly ordered fields a certain construction of non-commutative join hypergroups is presented based on the criterion of reproducibility of semi-hypergroups which are determined by ordered semigroups. The aim of

Constructions of positive commutative semigroups on the plane, II
International Journal of Mathematics and Mathematical Sciences, 1985 A positive semiroup is a topological semigroup containing a subsemigroup N isomorphic to the multiplicative semigroup of nonnegative real numbers, embedded as a closed subset of E2 in such a way that 1 is an identity and 0 is a zero.

Superextensions of cyclic semigroups
Karpatsʹkì Matematičnì Publìkacìï, 2013 Given a cyclic semigroup $S$ we study right and left zeros, singleton left ideals, the minimal ideal, left cancelable and right cancelable elements of superextensions $\lambda(S)$ and characterize cyclic semigroups whose superextensions are commutative.

Totally commutative semigroups [PDF]
Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1991 AbstractA semigroup is totally commutative if each of its essentially binary polynomials is commutative, or equivalently, if in every polynomial (word) every two essential variables commute. In the present paper we describe all varieties (equational classes) of totally commutative semigroups, lattices of subvarieties for any variety, and their free ...
