Series in Algebra - Vol. 3 FINITE SEMIGROUPS AND UNIVERSAL ALGEBRA by Jorge Almeida (Univ. Porto) Motivated by applications in theoretical computer science, the theory of finite semigroups has emerged in recent years as an autonomous area of mathematics. It fruitfully combines methods, ideas and constructions from algebra, combinatorics, logic and topology. 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. Besides providing a foundational study of the theory in the setting of arbitrary abstract finite algebras, this book stresses the syntactical approach to finite semigroups. This involves studying (relatively) free and profinite free semigroups and their presentations. The techniques used are illustrated in a systematic study of various operators on pseudovarieties of semigroups. Contents: Finite Universal Algebra: Elements of Universal Algebra Order and Topology Finite Algebras Decidability Finite Semigroups and Monoids: Preliminaries Permutativity Operators Relating Semigroups and Monoids Semigroups Whose Regular D-Classes are Subsemigroups The Join The Semidirect Product The Power Factorization of Implicit Operations Open Problems

Universal algebra Universal algebra is the field of mathematics that studies the ideas common to all algebraic structures From the point of view of universal algebra, an algebra is a set A together with a collection of operations on A . An n ary operation on A is a function that takes n elements of A and returns a single element of A . Thus, a 0-ary operation (or nullary operation ) is simply an element of A , or a constant , often denoted by a letter like a . A 1-ary operation (or unary operation ) is simply a function from A to A , often denoted by a symbol placed in front of its argument, like ~ x . A 2-ary operation (or binary operation ) is often denoted by a symbol placed between its arguments, like x y . Operations of higher or unspecified arity are usually denoted by function symbols, with the arguments placed in parentheses and separated by commas, like f x y z ) or f x x n After the operations have been specified, the nature of the algebra can be further limited by axioms , which in universal algebra must take the form of equational laws. An example is the associative axiom for a binary operation, which is given by the equation

Geometry Section : Research General Introduction Announcements People Scientific staff Ph.D. students Education Courses Research Research Publications Links Universal Algebra and Logic There has been a shift of interests towards relation algebra and logic in the last few years. This is due in part to the supervising of - and participating in - M. El Bachraoui's Ph.D. research in the area of relation algebra. The running project is currently suspended, though there may be occasional future work in the field of convex geometry. The project universal algebra and logic is basically involved with Tarski's relation algebras, which provide an algebraic model of a Boolean algebra of binary relations with composition and reverse operators. The joint research of M. El Bachraoui and M. van de Vel has sofar been directed to questions on representability (when does an algebra models a Boolean algebra with genuine binary relations), degree (how many variables are required for the statements and proofs of results in a particular subtheory), and tensor products (a general construction capturing matrix relation algebras and other derived constructions). The language and logic of relation algebra was used by Tarski for a faithful embedding of set theory and of number theory. Recently, M. van de Vel extended this result to obtain a faithful translation of any first order theory into a theory of relation algebra with features (allowing record-like constructs in the language). The language of relation algebra with features seems particularly appropriate to express programming constructs like

Plotkin Hebrew University, Jerusalem, Israel Book Series: MATHEMATICS AND ITS APPLICATIONS Volume 272 This volume is devoted to the development of an algebraic model of databases. The first chapter presents a general introduction. The following sixteen chapters are divided into three main parts. Part I deals with various aspects of universal algebra. The chapters of Part I discuss topics such as sets, algebras and models, fundamental structures, categories, the category of sets, topoi, fuzzy sets, varieties of algebras, axiomatic classes, category algebra and algebraic theories. Part II deals with different approaches to the algebraization of predicate calculus. This material is intended to be applied chiefly to databases, although some discussion of pure algebraic applications is also given. Discussed here are topics such as Boolean algebras and propositional calculus, Halmos algebras and predicate calculus, connections with model theory, and the categorial approach to algebraic logic. Part III is concerned specifically with the algebraic model of databases, which considers the database as an algebraic structure. Topics dealt with in this part are the algebraic aspects of databases, their equivalence and restructuring, symmetries and the Galois theory of databases, and constructions in database theory. The volume closes with a discussion and conclusions, and an extensive bibliography.

Elementary Universal Algebra and Computer Science Eric G. Wagner, Wagner Mathematics Universal algebra is a branch of mathematics which was originally concerned with abstract generalizations of algebraic concepts. It is perhaps surprising then that the ideas of universal algebra have played a significant role in such areas of computer science as the specification of data types, the semantics of programming languages, and the theory of compilers. Equally surprising is that the seemingly abstract fundamental constructs of universal algebra can be easily implemented on a computer using a symbolic computation system such as Mathematica in a manner that makes it possible to construct and explore interesting computer science examples. In this talk we will give an introduction to universal algebra for non-mathematicians, illustrate its application to the syntax and semantics of programming languages, and describe how the basic constructs of universal algebra can be implemented within Mathematica. Demonstrations of the Mathematica programs (notebooks) implementing the material in the talk will be given on a later date and, if there is sufficient interest, more detailed talks may also be given.
