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

Extractions: 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.

Any suggestions appreciated. I wrote a simple Perl script which reads a Cayley table of a groupoid and converts it into input files for the following programs: UAcalc, Mace and Jezek's G. It can thus be used easily (with Mace) for checking identities or completing partial groupoids within a given equational theory.

"...abstract algebras are divided by a very simple scheme into self-contained `species'. Within each species a perfect duality is found between families of formal laws and the families of algebras satisfying them. Here the term 'family of algebras of a given species' is used in a technical sense meaning a class closed under taking subalgebras, homomorphic images and direct products - or what is nowadays called a variety. This said, one must point out that undoubtedly the most influential figure in the movement towards abstraction and generality in algebra which culminated in Universal Algebra was Emmy Noether, who died in 1935."

Extractions: J Austral Math Soc Ser A A Natural Representation of Partitions as Terms of a Universal Algebra Harry Lakser (Received 17 September 1990) We consider a variety of algebras with two binary commutative and associative operations. For each integer n 0, we represent the partitions on an n -element set as n -ary terms in the variety. We determine necessary and sufficient conditions on the variety ensuring that, for each n , these representing terms be all the essentially n -ary terms and moreover that distinct partitions yield distinct terms.

Extractions: Name: Istvan Heckenberger, WIS Title:Introduction to Nichols algebras. Abstract: Nichols algebras naturally appear in the classification of pointed Hopf algebras. Prominent examples are the symmetric and exterior algebras of a vector space, and the quantized enveloping algebras U_q(n^+). In this talk several results on the structure of Nichols algebras are introduced and the relation of Nichols algebras and semisimple Lie algebras is pointed out. Recently found tools for the classification of Nichols algebras are presented.

Extractions: Main [via via Jan Anderssen Something I should add to my semantic resources page: Stanley N. Burris and H.P. Sankappanavar have made their book A Course in Universal Algebra (originally Springer 1981, now out of print) available for free online. Lots of good stuff on lattices, Boolean algebras, etc. They write: Feel free to download and print off your own copy. And be sure to tell others that this text is once again available! Colleagues have noted the value of downloading a copy and attaching it to their webpage, especially for the benefit of their students who may not have fast access to this site. Please feel free to do this as well. And it would be appreciated if you put a link to this site, www.thoralf.uwaterloo.ca, on your web page so your students can easily find the other files and interactive programs available here. Stanley Burris indeed has an interesting website with papers and lecture notes. What I find most interesting are his materials on the history of mathematical logic. It has been a plan of mine for a while to dig into the archaeology of semantics, as a fun kind of project. Kind of like what Jeff Miller has done for mathematics with his pages: 05.01.03 @ 09:53 PM
