Commutative of factoriza­ semigroups provide a natural setting and a useful tool for the study tion in rings. Additive subsemigroups of N and Nn have close ties to algebraic geometry. Commutative rings are constructed from commutative semigroups as semigroup algebras or power series s: 1. Multivariate cryptography contains studies of cryptographic applications of subsemigroups and subgroups of affine Cremona semigroups defined over finite commutative ring K. We consider special semigroups of transformations of the variety (K*)n, K=F q or .

### Semigroups with a system of subsemigroups by Stojan BogdanovicМЃ Download PDF EPUB FB2

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. In mathematics, a semigroup is an algebraic structure consisting of a set together with an associative binary operation. The binary operation of a semigroup is most often denoted multiplicatively: xy, or simply xy, denotes the result of applying the semigroup operation to the ordered pair (x, y).Associativity is formally expressed as that (xy)z = x(yz) for all x, y and z in the.

This book is concerned with the structure of linear semigroups, that is, subsemigroups of the multiplicative semigroup Mn(K) of n × n matrices over a field K (or, more generally, skew linear semigroups -- if K is allowed to be a division ring) and its applications to certain problems on associative algebras, semigroups and linear by: 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 ways, using either algebraic notions or topological notions. Varieties of finite monoids, varieties of finite ordered semigroups and varieties of finite ordered monoids are defined similarly. Specifically, if the group G in question and the subsemigroup S are both affine algebraic varieties the S is in fact a subgroup.

This fact is well known in the theory of algebraic semigroups and a consequence of a theorem on subsemigroups of algebraic Lie groups published by C. Chevalley in the second volume of his book on Lie groups in [2]. Abstract. As we mentioned in the Preface, one can treat inverse semigroups as unary semi-groups, i.e.

as algebraic systems with two operations: the binary operation of multiplication and the unary operation of taking the inverse element.

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. This journal serves as a platform for the speedy and efficient transmission of information on current research in semigroup theory.

Coverage in the journal includes: algebraic semigroups, topological semigroups, partially ordered semigroups, semigroups of measures and harmonic analysis on semigroups, transformation semigroups, semigroups of operators, and applications of.On finite complete rewriting systems and large subsemigroups, J.

Algebra (), – Recommend this journal Email your librarian or administrator to recommend adding this journal to your organisation's collection. It covers the following topics on the examples of the three classical finite transformation semigroups: transformations and semigroups, ideals and Green's relations, subsemigroups, congruences, endomorphisms, nilpotent subsemigroups, presentations, actions on sets, linear representations, cross-sections and variants.

The book contains many. One part relates to computing the maximal subsemigroups of a special class of semigroups, known as Rees 0-matrix semigroups. The other part involves a careful analysis of certain graphs associated to the semigroup S, which, roughly speaking, capture the essential information about the action of S on its J.

We develop a general approach to the study of maximal nilpotent subsemigroups of finite semigroups. This approach can be used to recover many known classifications of maximal nilpotent. Gathers and unifies the results of the theory of noncommutative semigroup rings, primarily drawing on the literature of the last 10 years, and including several.

This book is concerned with the structure of linear semigroups, that is, subsemigroups of the multiplicative semigroup M n (K) of n × n matrices over a field K (or, more generally, skew linear semigroups — if K is allowed to be a division ring) and its applications to certain problems on associative algebras, semigroups and linear.

Subsemigroups of finite-dimensional Lie groups that are generated by one-parameter semigroups are the subject of this book. It covers basic Lie theory for such semigroups and some closely related topics.

These include ordered homogeneous manifolds, where the order is defined by a field of cones, invariant cones in Lie algebras and associated Ol. Definition. A semigroup is a set S together with a binary operation " \cdot" (that is, a function \cdot:S\times S\rightarrow S) that satisfies the associative property.

For all a,b,c\in S, the equation (a\cdot b)\cdot c = a\cdot(b\cdot c) holds. More succinctly, a semigroup is an associative magma. Examples of semigroups. Empty semigroup: the empty set forms a semigroup with the empty. It covers the following topics on the examples of the three classical finite transformation semigroups: transformations and semigroups, ideals and Green\'s relations, subsemigroups, congruences, endomorphisms, nilpotent subsemigroups, presentations, actions on sets, linear representations, cross-sections and variants.
