  • CERTAIN FUNDAMENTAL CONGRUENCES on a REGULAR SEMIGROUP! by J
    CERTAIN FUNDAMENTAL CONGRUENCES ON A REGULAR SEMIGROUP! by J. M. HOWIE and G. LALLEMENT (Received 21 June, 1965) In recent developments in the algebraic theory of semigroups attention has been focussing increasingly on the study of congruences, in particular on lattice-theoretic properties of the lattice of congruences. In most cases it has been found advantageous to impose some re- striction on the type of semigroup considered, such as regularity, commutativity, or the property of being an inverse semigroup, and one of the principal tools has been the consideration of special congruences. For example, the minimum group congruence on an inverse semigroup has been studied by Vagner [21] and Munn [13], the maximum idempotent-separating con- gruence on a regular or inverse semigroup by the authors separately [9, 10] and by Munn [14], and the minimum semilattice congruence on a general or commutative semigroup by Tamura and Kimura [19], Yamada [22], Clifford [3] and Petrich [15]. In this paper we study regular semigroups and our primary concern is with the minimum group congruence, the minimum band congruence and the minimum semilattice congruence, which we shall con- sistently denote by a, P and t] respectively. In § 1 we establish connections between /? and t\ on the one hand and the equivalence relations of Green [7] (see also Clifford and Preston [4, § 2.1]) on the other. If for any relation H on a semigroup S we denote by K* the congruence on S generated by H, then, in the usual notation, In § 2 we show that the intersection of a with jS is the smallest congruence p on S for which Sip is a UBG-semigroup, that is, a band of groups [4, p.

  • EMBEDDING ANY COUNTABLE SEMIGROUP WITHOUT IDEMPOTENTS in a 2-GENERATED SIMPLE SEMIGROUP WITHOUT IDEMPOTENTS by KARL BYLEEN (Received 2 June, 1986)
    EMBEDDING ANY COUNTABLE SEMIGROUP WITHOUT IDEMPOTENTS IN A 2-GENERATED SIMPLE SEMIGROUP WITHOUT IDEMPOTENTS by KARL BYLEEN (Received 2 June, 1986) Although the classes of regular simple semigroups and simple semigroups without idempotents are evidently at opposite ends of the spectrum of simple semigroups, their theories involve some interesting connections. Jones [5] has obtained analogues of the bicyclic semigroup for simple semigroups without idempotents. Megyesi and Polldk [7] have classified all combinatorial simple principal ideal semigroups on two generators, showing that all are homomorphic images of one such semigroup Po which has no idempotents. In an earlier paper [1] a construction designed to produce regular simple semigroups was used to show that any countable semigroup can be embedded in a 2-generated bisimple monoid. In this paper a modification of the earlier construction is employed to prove that any countable semigroup without idempotents can be embedded in a 2-generated simple semigroup without idempotents, and to produce certain 2-generated congruence-free semigroups. The reader is referred to the survey paper by Hall [3] and to Chapter 4 of Lyndon and Schupp [6] for discussions of related embedding theorems for semigroups, inverse semigroups, and groups. These references also contain extensive bibliographies. Clifford and Preston [2] or Howie [4] may be consulted for standard definitions and results from the theory of semigroups. The author thanks Peter R. Jones for many helpful discussions. 1. The construction. Let (S, •) be any semigroup and let A and B be nonempty sets which are disjoint from each other and from S. Let a:A x S—*A be a right action of S on A (i.e., a\>(s • t) = (aV>s)\>t for all a eA and s, teS, where a\>s denotes (a, s)a).

For example, it can be found in parts of computer science, more specifically the concepts of finite state automata and the study of formal languages[1]. This project shall discuss the history of the field, and then we shall discuss some basic definitions of groups and semigroups to lay the foundations needed for the rest of this report. From there we will discuss the partial order, which is a concept that arises often in regards to semigroups and inverse semigroups. Then we shall discuss some well-known theorems, namely Cayley's theorem, an important theorem for groups, and the semigroup analogue in the faithful representation theorem for full transformation monoids. After this we shall discuss inverse semigroups, explore the natural partial order, which is a partial order restricted to E(S) which works very nicely in inverse semigroups.

  • Properties of Relatively Free Inverse Semigroups by N
    TRANSACTIONS OF THE AMERICAN MATHEMATICAL SOCIETY Volume 294, Number 1, March 1986 PROPERTIES OF RELATIVELY FREE INVERSE SEMIGROUPS BY N. R. REILLY AND P. G. TROTTER ABSTRACT. The objective of this paper is to study structural properties of relatively free inverse semigroups in varieties of inverse semigroups. It is shown, for example, that if S is combinatorial (i.e., X is trivial), completely semisimple (i.e., every principal factor is a Brandt semigroup or, equivalently, S does not contain a copy of the bicyclic semigroup) or F-unitary (i.e., E(S) is the kernel of the minimum group congruence) then the relatively free inverse semigroup F"Vx on the set X in the variety "V generated by S is also combinatorial, completely semisimple or F-unitary, respectively. If 5 is a fundamental (i.e., the only congruence contained in M is the identity- congruence) and \X\ > No, then FVx ia a'so fundamental. FVx may not be fundamental if |^f| < No- It is also shown that for any variety of groups U and for |X| > No, there exists a variety of inverse semigroups "V which is minimal with respect to the properties (i) FVx ls fundamental and (ii) "V n Q = U, where Q is the variety of groups. In the main result of the paper it is shown that there exists a variety V for which FVx 's not completely semisimple, thereby refuting a long standing conjecture. 1. Summary. In general, the relatively free objects in any variety of algebras are important in the study of that variety and this has been true, in particular, in the study of inverse semigroups.

  • On Semigroups with Lower Semimodular Lattice of Subsemigroups Peter R
    Marquette University e-Publications@Marquette Mathematics, Statistics and Computer Science Mathematics, Statistics and Computer Science, Faculty Research and Publications Department of 11-1-2010 On Semigroups with Lower Semimodular Lattice of Subsemigroups Peter R. Jones Marquette University, [email protected] Accepted version. Journal of Algebra, Vol. 324, No. 9 (November 1, 2010). DOI. © 2010 Elsevier. Used with permission. On semigroups with lower semimodular lattice of subsemigroups. Peter R. Jones January 11, 2010 Abstract The question of which semigroups have lower semimodular lattice of subsemigroups has been open since the early 1960's, when the corresponding question was answered for modularity and for upper semimodularity. We provide a characterization of such semigroups in the language of principal factors. Since it is easily seen (and has long been known) that semigroups for which Green's relation J is trivial have this property, a description in such terms is natural. In the case of periodic semigroups | a case that turns out to include all eventually regular semigroups | the characterization becomes quite explicit and yields interesting consequences. In the general case, it remains an open question whether there exists a simple, but not completely simple, semigroup with this property. Any such semigroup must at least be idempotent-free and D-trivial. 1 Introduction. The lattice L(S) of subsemigroups of a semigroup S has been a topic of intense study since the 1960's [11]. Those semigroups for which this lattice satisfies common lattice-theoretic properties such as distributivity, modularity and upper semimodularity were determined in the early years of that decade. As noted in [11, x5.14], little is known | or at least little is published | about lower semimodularity in this context, other than that an apparently diverse array of semigroups do have subsemigroup lattices with this property.

  • THE FREE MONOGENIC INVERSE SEMIGROUP and the BICYCLIC MULTIPLICATION 1. Introduction
    Ann. Sci. Math. Québec 36, No 1, (2012), 235–243 THE FREE MONOGENIC INVERSE SEMIGROUP AND THE BICYCLIC MULTIPLICATION EMIL DANIEL SCHWAB RÉSUMÉ. Dans la théorie des semi-groupes inverses, une attention spéciale est donnée aux semi-groupes inverses libres, et plus particulièrement au semi-groupe in- verse libre monogénique. Celui-ci admet un nombre intéressant de copies isomorphes et Petrich a présenté la construction de cinq d’entre elles. Dans cet article, nous pré- sentons la construction d’une nouvelle copie isomorphe du semi-groupe inverse libre monogénique dont le produit implique uniquement la multiplication bicyclique. La construction est élémentaire et fait appel à la propriété universelle d’un objet libre. Ceci permet à l’article d’être indépendant des autres constructions apparaissant dans la littérature en lien avec la théorie des semi-groupes inverses libres. ABSTRACT. In the theory of inverse semigroups, a special attention is given to free inverse semigroups, in particular to the free monogenic inverse semigroup. The free monogenic inverse semigroup admits a number of interesting isomorphic copies. Petrich has presented the constructions of five isomorphic copies of the free monogenic inverse semigroup. In this paper we give a new isomorphic copy of the free monogenic inverse semigroup with a product involving only the bicyclic multiplication. Using an elementary way based on the universal property of a free object, the paper is organized so as to be self-contained; it is not dependent on other constructions from the theory of free inverse semigroups. 1. Introduction An inverse semigroup S is a semigroup in which every element s in S has a unique generalized inverse x in S, in the sense that s = sxs and x = xsx.

  • CONGRUENCES and GREEN's RELATIONS on REGULAR SEMIGROUPS Byt
    CONGRUENCES AND GREEN'S RELATIONS ON REGULAR SEMIGROUPS byT. E. HALL| (Received 10 December, 1970; revised 12 June, 1971) 1. Introduction. It is sometimes possible to reconstruct semigroups from some of their homomorphic images. Some recent examples have been the construction of bisimple inverse semigroups from fundamental bisimple inverse semigroups [9], and the construction of generalized inverse semigroups from inverse semigroups [12]. The success of this method depends on a knowledge of the similarities between the semigroup and its homomorphic image. We therefore examine in this paper the relationship between Green's relations on a regular semigroup and Green's relations on any homomorphic image. We now state the main specific question that we consider. Let Jf be any one of Green's relations 34?, £P, 52, @> and / and let p be a congruence on a regular semigroup S. QUESTION. If A and B are elements of Sjp that are tf-related in S/p, then are there elements aeA, beB such that a and b are tf-related in SI We find that the answer is yes for i£, Si and 2) and no for Jf and /. Many related questions are considered. The partial analysis given leads to new proofs of many known results about congruences on regular semigroups. In the final section semigroups other than regular semigroups are considered. 2. Preliminaries. We shall use whenever possible, and usually without comment, the notations of Clifford and Preston [1]. Further, for any semigroup S we define a relation "V by •f = {(a, b)eSx S : aba = a and bab = b}.

  • On Semitopological Bicyclic Extensions of Linearly Ordered Groups
    ON SEMITOPOLOGICAL BICYCLIC EXTENSIONS OF LINEARLY ORDERED GROUPS OLEG GUTIK AND KATERYNA MAKSYMYK Abstract. For a linearly ordered group G let us define a subset A ⊆ G to be a shift-set if for any x,y,z ∈ A with y < x we get x · y−1 · z ∈ A. We describe the natural partial order and solutions of equations on the semigroup B(A) of shifts of positive cones of A. We study topologizations of the semigroup B(A). In particular, we show that for an arbitrary countable linearly ordered group G and a non-empty shift-set A of G every Baire shift-continuous T1-topology τ on B(A) is discrete. Also we prove that for an arbitrary linearly non-densely ordered group G and a non-empty shift-set A of G, every shift-continuous Hausdorff topology τ on the semigroup B(A) is discrete, and hence (B(A), τ) is a discrete subspace of any Hausdorff semitopological semigroup which contains B(A) as a subsemigroup. 1. Introduction and preliminaries We shall follow the terminology of [14, 18, 20, 24, 33, 40, 41]. A semigroup is a non-empty set with a binary associative operation. A semigroup S is called inverse if for any x ∈ S there exists a unique y ∈ S such that x · y · x = x and y · x · y = y. Such an element y in S is called the inverse of x and is denoted by x−1. The map defined on an inverse semigroup S which maps every element x of S to its inverse x−1 is called the inversion.

    International conference held online at UniwersytetL´odzki, L´od´z,Poland BOOK OF ABSTRACTS 1 Dynamics of (Semi{)Group Actions The modern theory of dynamical systems encompasses the study of group and semi-group actions, which include vibrant, exciting, and very active lines of research. The primary aim of the conference is to bring together mathematicians involved in topological, mea- surable and algebraic aspects of dynamical systems generated by (semi-)group actions, to stimulate the exchange of new ideas and to offer new opportunities for broadening scientific contacts. This is reflected by the inclusion of young and experienced researchers giving plenary talks and contributed talks. The scope of this conference encompasses research of the dynamical, geometric and algebraic aspects of semi-group actions by continuous mappings of real or complex variables. The wide range of topics include thermodynamic formalism for random dynamical systems, fractal dimension of self-similar sets, entropy and pressure functionals for semigroup actions, topological and ergodic aspects of algebraic actions, among many others. This is the second edition of the conference (the first one took place inL´od´zon 2019). We wish you a pleasant and fruitful (even if online) participation.
