Endomorphism monoids of semilattices of semigroups
Науковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017 We prove that the endomorphism monoid of a semilattice of semigroups, which are semilattice indecomposable, is isomorphically embedded into the wreath product of a transformation semigroup with a small category.

Generating continuous mappings with Lipschitz mappings [PDF]
, 2007 If X is a metric space, then C-X and L-X denote the semigroups of continuous and Lipschitz mappings, respectively, from X to itself. The relative rank of C-X modulo L-X is the least cardinality of any set U\L-X where U generates C-X. For a large class of

On the Transformation Semigroups of Finite Automata
Journal of Computer and System Sciences, 1983 AbstractNecessary and sufficient conditions for a given automaton to be of left identity type, of identity type, of right group type, of group type quasi state independent, and state independent are presented. The time required to decide whether or not each condition holds for a given automaton is also estimated under the uniform cost criterion.

Regularity of Semigroups of Transformations Whose Characters Form the Semigroup of a Δ-Structure
International Journal of Mathematics and Mathematical Sciences, 2020 In this paper, we make use of the notion of the character of a transformation on a fixed set X, provided by Purisang and Rakbud in 2016, and the notion of a Δ-structure on X, provided by Magill Jr.

On the multiplicity order of spinnable star-like transformation semigroup Tw*n
Journal of Nigerian Society of Physical SciencesThe application of graph theory has gained significant traction within the realm of the algebraic theory of semigroups. This study delves into exploring the geometric properties of the star-like transformation semigroup \alpha\omega_n^*, a distinctive ...

On Some Numerical Semigroup Transforms
Algebra Colloquium, 2022 In this paper we introduce a particular semigroup transform [Formula: see text] that fixes the invariants involved in Wilf's conjecture, except the embedding dimension. It also allows one to arrange the set of non-ordinary and non-irreducible numerical semigroups in a family of rooted trees.

Maximal subgroups of free idempotent-generated semigroups over the full transformation monoid
, 2011 Let Tn be the full transformation semigroup of all mappings from the set {1, . . . , n} to itself under composition. Let E = E(Tn) denote the set of idempotents of Tn and let e ∈ E be an arbitrary idempotent satisfying |im (e)| = r ≤ n − 2. We prove that
