On Magnifying Elements in E-Preserving Partial Transformation Semigroups
Mathematics, 2018 Let S be a semigroup. An element a of S is called a right [left] magnifying element if there exists a proper subset M of S satisfying S = M a [ S = a M ] . Let E be an equivalence relation on a nonempty set X.

Skew Pairs of Idempotents in Partial Transformation Semigroups
Mathematics, 2021 Let S be a regular semigroup. A pair (e,f) of idempotents of S is said to be a skew pair of idempotents if fe is idempotent, but ef is not. T. S. Blyth and M. H. Almeida (T. S. Blyth and M. H.

Transformation Representations of Sandwich Semigroups [PDF]
Experimental Mathematics, 2018 Let $a$ be an element of a semigroup $S$. The local subsemigroup of $S$ with respect to $a$ is the subsemigroup $aSa$ of $S$. The variant of $S$ with respect to $a$ is the semigroup with underlying set $S$ and operation $\star_a$ defined by $x\star_ay=xay$ for $x,y\in S$.

Regularity and Green's Relations on a Semigroup of Transformations with Restricted Range
International Journal of Mathematics and Mathematical Sciences, 2008 Let T(X) be the full transformation semigroup on the set X and let T(X,Y)={α∈T(X):Xα⊆Y}. Then T(X,Y) is a sub-semigroup of T(X) determined by a nonempty subset Y of X.

Thickness in topological transformation semigroups
International Journal of Mathematics and Mathematical Sciences, 1993 This article deals with thickness in topological transformation semigroups (τ-semigroups). Thickness is used to establish conditions guaranteeing an invariant mean on a function space defined on a τ-semigroup if there exists an invariant mean on its ...

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.

Tropical Polynomial of Partial Contraction Transformation Semigroup
, 2023 In this paper, we used tropical geometry on a partial transformation semigroup to create a tropical polynomial on a partial contraction mapping. Then we used the tropical polynomial to obtain a contraction mapping and plot tropical curves.
