Representation theory of finite semigroups over semirings [PDF]
We develop the representation theory of a finite semigroup over an arbitrary commutative semiring with unit, in particular classifying the irreducible and minimal representations. The results for an arbitrary semiring are as good as the results for a field.

Fuzzy semigroup is an algebraic extension of semigroup. It has found application in fuzzy coding theory, fuzzy nite state machines and fuzzy languages. In this paper, a comprehensive literature review on fuzzy semigroup theory is realized.

Action graph of a semigroup act & its functorial connection [PDF]
In this paper we define C-induced action graph G(S,a,C;A) corresponding to a semigroup act (S,a,A) and a subset C of S. This generalizes many interesting graphs including Cayley Graph of groups and semigroups, Transformation Graphs (TRAG), Group Action ...

The Source of Semiprimeness of Semigroups
In this study, we define new semigroup structures using the set SS=a∈S|aSa=0 which is called the source of semiprimeness for a semigroup S with zero element.

A-ideals and fuzzy A-ideals of ternary semigroups [PDF]
A ternary semigroup is a nonempty set together with a ternary multiplication that is associative. Every semigroup can be reduced to a ternary semigroup, but a ternary semigroup does not necessarily reduce to a semigroup.

Representation theory of finite semigroups, semigroup radicals and formal language theory [PDF]
In this paper we characterize the congruence associated to the direct sum of all irreducible representations of a finite semigroup over an arbitrary field, generalizing results of Rhodes for the field of complex numbers. Applications are given to obtain many new results, as well as easier proofs of several results in the literature, involving ...

Controllability of Nonlinear Boundary Value Control Systems in Banach Spaces Using Schauder Fixed Point Theorem [PDF]
In this paper, sufficient conditions for controllability of nonlinear boundary value control system in Banach spaces are established. The results are obtained by using semigroup theory “compact semigroup”and some techniques of nonlinear functional ...

Ramsey Theory for Layered Semigroups [PDF]
We further develop the theory of layered semigroups, as introduced by Farah, Hindman and McLeod, providing a general framework to prove Ramsey statements about such a semigroup $S$. By nonstandard and topological arguments, we show Ramsey statements on $S$ are implied by the existence of coherent sequences in $S$.

Ramsey Theory in Noncommutative Semigroups [PDF]
By utilizing ultrafilters we give a general version of the Central Sets Theorem [ 6 6 , Proposition 8.21]. This enables us to derive noncommutative versions of van der Waerden’s Theorem and several of its generalizations. We also derive some standard results, including the Hales-Jewett Theorem.
