Semigroups of order-decreasing transformations
, 2012 Let X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this Thesis the study of order-increasing full (partial, partial one-to-one) transformations has been

On Signed Full Transformation Semigroup of a Finite Set
If we define [n] = {1,2,3,...,n} and [n*] = {±1,±2,±3...,±n}. A map α: [n] → [n*] is called a signed transformation on [n]. The collection of all these maps together with composition forms a semigroup called a signed transformation semigroup. Given that

Two-Sided Zero-Divisor Graphs of Order-Preserving and A-Decreasing Finite Transformation Semigroups
AxiomsLet On(A) be the order-preserving and A-decreasing finite transformation semigroup on Xn = {1, 2, …, n}. It is known that On(A) has zero element if and only if 1 ∈ A. In this paper, we investigate zero-divisor graphs of On(A) where 1 ∈ A and n ≥ 4. First,

UNIVERSAL COMPACTIFICATIONS OF TRANSFORMATION SEMIGROUPS [PDF]
Journal of Sciences, Islamic Republic of Iran, 2000 We extend the notion of semigroup compactification to the class of transformation semigroups, and determine the compactifications which are universal with respect to some topological properties.

Journal of Nigerian Society of Physical SciencesAn efficient and mathematically sound method for simulating the distributions of telecommunication signals is the star-like semigroup convolution model. A rigorous operator-theoretic measure of signal strength is provided by the (S3I), which is obtained ...

The Algebraic View of Computation: Implementation, Interpretation and Time
Philosophies, 2018 Computational implementations are special relations between what is computed and what computes it. Though the word “isomorphism” appears in philosophical discussions about the nature of implementations, it is used only metaphorically. Here we

Open MathematicsLet T(X) be a full transformation semigroup on a nonempty set X. The Cayley digraph Γ of a semigroup T(X) with respect to the Green’s L $\mathcal{L}$ -class is a digraph with vertex set T(X) and two vertices α, β ∈ T(X) are adjacent as an arc (α, β ...

On the Syntactic Monoids Associated with a Class of Synchronized Codes
The Scientific World Journal, 2013 A complete code C over an alphabet A is called synchronized if there exist x,y∈C* such that xA*∩A*y⊆C*. In this paper we describe the syntactic monoid Syn(C+) of C+ for a complete synchronized code C over A such that C+, the semigroup generated by C, is ...
