    A semigroup is an algebraic structure consisting of a set together with an associative binary operation. A semigroup with an identity element is called monoid. This tag is most frequently used for questions related to the concept of semigroups in the context of abstract algebra. "Numerical Semigroups" is accessible to first year graduate students, with only a basic knowledge of algebra required, giving the full background needed for readers not familiar with the topic. Researchers will find the tools presented useful in producing examples and counterexamples in other fields such as algebraic geometry, number theory.

    Linear Associative Algebras focuses on finite dimensional linear associative algebras and the Wedderburn structure theorems. The publication first elaborates on semigroups and groups, rings and fields, direct sum and tensor product of rings, and polynomial and matrix rings. This comprehensive, encyclopedic text in four parts aims to give the reader - from the graduate student to the researcher/practitioner - a detailed understanding of modern finite semigroup theory, focusing in particular on advanced topics on the cutting edge of research. The q-theory of Finite Semigroups presents important techniques and results, many for the first time in book form, thereby.

    The basic structure theories for groups and semigroups are quite different - one uses the ideal structure of a semigroup to give information about the semigroup for ex- ample - and the study of homomorphisms between semigroups is complicated by the fact that a. Additional features: (1) For newcomers, an appendix on elementary finite semigroup theory; (2) Extensive bibliography and index.

Abstract. In this expository paper, we use a naive approach to the structure of inverse semigroups to motivate the introduction of P-semigroups and E-unitary inverse semigroups.A proof of the so-called P-theorem, due to W.D.

Munn, is used to simplify some existing results on inverse subsemigroups of, and congruences on, E-unitary inverse semigroups.

In mathematics, and more precisely in semigroup theory, a variety of finite semigroups is a class of semigroups having some nice algebraic properties.

Those classes can be defined in two distinct way, using either algebraic notions or topological notions. Varieties of finite monoids, varieties of finite ordered semigroups and varieties of finite ordered On the structure of finite semigroups.

book are defined similarly. The first book on commutative semigroups was Redei's The theory ly generated commutative semigroups, published in Budapest in Subsequent years have brought much progress.

By the structure of finite commutative semigroups was fairly well understood. Recent results have perfected this understanding and extended it to finitely generated semigroups.

It is shown that properties of the structure of a finite semigroup S such as the order of the set ofJ of S and the existence of normal subsemigroups may be deduced from the knowledge of the characters of the irreducible representations of S.

Many structure theorems on regular and commutative semigroups are introduced.;College or university bookstores may order five or more copies at a special student price which is available upon request from Marcel Dekker, Inc.

A semigroup homomorphism is a function that preserves semigroup structure. ("On finite groups without the rule of unique invertibility") determined the structure of finite simple semigroups and showed that the minimal ideal (or Green's relations J-class) of a finite semigroup is simple.

In this paper algorithms are described for computing the equivalence classes induced by the Green relations on the elements of a finite semigroup. This is a preview of. In simple terms, the theory aims at a classification of finite semigroups in certain classes called "pseudovarieties".

The classifying characteristics have both structural and syntactical aspects, the general connection between them being part of universal algebra. Buy Semigroups: An Introduction to the Structure Theory (Chapman & Hall/CRC Pure and Applied Mathematics) on FREE SHIPPING on qualified orders.

PREFACE So far as we know, the term "semigroup" first appeared in mathematical literature on page 8 of J.-A. de Siguier's book, filaments de la Theorie des Groupes Abstraits (Paris, ), and the first paper about semigroups was a brief one by L.

Commutative semigroups are more important than is suggested by the stan­ dard examples ofsemigroups, which consist ofvarious kinds oftransformations or arise 4/5(1). This book gives a gentle but up-to-date introduction into the theory of operator semigroups (or linear dynamical systems), which can be used with great success to describe the dynamics of complicated phenomena arising in many applications.
