Graphs Connected to Isotopes of Inverse Property Quasigroups: A Few Applications
Journal of Applied Mathematics, Volume 2024, Issue 1, 2024.Many real‐world applications can be modelled as graphs or networks, including social networks and biological networks. The theory of algebraic combinatorics provides tools to analyze the functioning of these networks, and it also contributes to the understanding of complex systems and their dynamics.

Embedding finite and infinite words into overlapping tiles [PDF]
, 2014 International audienceIn this paper, we study languages of finite and infinite birooted words. We show how the embedding of free ω-semigroups of finite and infinite words into the monoid of birooted words can be generalized to the embedding of two-sorted

On ∼n Notion of Conjugacy in Some Classes of Epigroups
Journal of Mathematics, Volume 2024, Issue 1, 2024.The action of any group on itself by conjugation and the corresponding conjugacy relation plays an important role in group theory. Generalizing the group theoretic notion of conjugacy to semigroups is one of the interesting problems, and semigroup theorists had produced substantial amount of research in this direction.

Characterizations of totally ordered sets by their various endomorphisms [PDF]
, 2002 summary:We characterize totally ordered sets within the class of all ordered sets containing at least three-element chains using a simple relationship between their isotone transformations and the so called 2-, 3-, 4-endomorphisms which are introduced in

Ordered Categories and Ordered Semigroups [PDF]
We use ordered categories to study semidirect decompositions of nite ordered semigroups. We obtain ordered analogues of the derived category theorem and of the delay theorem.

A groupoid approach to regular *-semigroups [PDF]
In this paper we develop a new groupoid-based structure theory for the class of regular ⁎-semigroups. This class occupies something of a ‘sweet spot’ between the important classes of inverse and regular semigroups, and contains many natural examples ...

On Algebraic Semigroups and Monoids, II [PDF]
, 2014 International audienceConsider an algebraic semigroup $S$ and its closed subscheme of idempotents, $E(S)$. When $S$ is commutative, we show that $E(S)$ is finite and reduced; if in addition $S$ is irreducible, then $E(S)$ is contained in a smallest ...

A classification of rational languages by semilattice-ordered monoids [PDF]
, 2004 summary:We prove here an Eilenberg type theorem: the so-called conjunctive varieties of rational languages correspond to the pseudovarieties of finite semilattice-ordered monoids. Taking complements of members of a conjunctive variety of languages we get
