From relation to emulation: The Covering Lemma for transformation semigroups [PDF]

open access: yes, 1996
We define the kernel of a relational morphism of finite or infinite, faithful or non-faithful transformation semigroups. We prove the covering lemma for transformation semigroups, and a wreath product embedding theorem in terms of this kernel ...

Regularity of Semigroups of Transformations Whose Characters Form the Semigroup of a Δ-Structure

open access: yesInternational 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 maximum transform and semigroups of transformations [PDF]

open access: yesBulletin of the American Mathematical Society, 1962
Abstract : Part of the Project RAND research program consists of basic supporting studies in mathematics. A problem frequently occurring in applications is that of determining the maximum or minimum value of a function subject to prescribed constraints.

On the multiplicity order of spinnable star-like transformation semigroup Tw*n

open access: yesJournal of Nigerian Society of Physical Sciences
The 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

open access: yesAlgebra 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.

Abelian minimal transformation semigroups [PDF]

open access: yes, 1994
We study some basic dynamical properties of minimal abelian transformation semigroups such as proximal relation, the regional proximal relations and related ...

A Linear Generalization of the Nearly Gorenstein Property, With Applications to Veronese Subalgebras

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We study the nearly Gorenstein property for Veronese subalgebras of (semi‐)standard graded algebras. We introduce a condition (♮)$(\natural)$ for Cohen–Macaulay semi‐standard graded rings, motivated by the study of Ehrhart rings. We show that if a semi‐standard graded algebra R$ R$ satisfies (♮)$(\natural)$, then its Veronese subalgebras R(k)$

Composition of Fractional Integral and Derivative Operators: Summarised in Tables

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper compiles a complete, detailed list of composition properties for Riemann–Liouville fractional differintegrals, in all possible cases for orders anywhere in the complex plane, with the results presented clearly in a table for easy visual consumption.
