62. Signature (universal Algebra) —— 维客(wiki) Translate this page In mathematics, a signature for an algebraic structure A over an underlying set S is a list of the operations that characterize A, along with their arities. http://www.wiki.cn/wiki/Signature_(universal_algebra)

var skin = 'monobook';var stylepath = '/w/skins'; Views Signature (universal algebra) Jump to: navigation search In mathematics , a signature for an algebraic structure A over an underlying set S is a list of the operations that characterize A , along with their arities . Signatures are a key concept in universal algebra , and are also employed in model category , and type theory S , followed by the symbols for the operations characterizing A . An operation f of arity n , where n is a natural number , is a function f S n S . Distinguished members of S , such as identity elements , are treated as operations of arity 0. The arities make up the second list, called the type of A . The arities are listed in the same order as the corresponding operations. To list the operations defining A in declining order of arity is conventional but not required. The signature of an algebraic structure captures much of its essential nature apart from its axioms Example: an additive group over G G To allow for external operations , one considers structures whose universe is a union of several "sorts". (For example, a vector space may be conceived of as a 2-sorted algebra, with the two sorts "scalar" and "vector".) For each operation one has to prescribe which sorts are allowed as inputs, and which sort the output belongs to.

I've never come across this, what does it mean, do you have a link? A confusion here is that our analogy is comparing things from different levels. Algebra is usually thought of as a model, so it comes above logic in "reality". In our analogy, we are comparing it to logic, which is fine as it's only an analogy. But I don't think the analogy extends to having a completeness theorem for algebra. Paul. Sponsored Links Free braindumps Software forum Database administration forum

Web InteractiveCode.com Interactive Code Programming/Coding Google's Summer of Code How best to handle NIL in generics? How best to handle NIL in generics? Posted by Stefan Ram on October 16th, 2005 That is correct. This is, however, not my personal definition of function, but the most common definition in mathematics. In mathematics, the term "sequence" already has another meaning, and "list" is rarely used in that sense. The mathematical term might be "tuple". That is only one possibility to define functions of multiple arguments, and it would not be the way that I prefer. I'd rather prefer a definition as genuine multi-argument functions, i.e., So that the type of the function "single-argument" or "multi-argument" is part of the function itself, not of its interpretation. For the same reason, I prefer not to define a triple ( a, b, c ) as the pair (( a, b ), c ), but as a distinct entity, and I do not like to define a pair as a set: the following assertion is true: - "(a, b, c)" is a pair.

Information Technology implications for Mathematics a view from the French riviera Marco Maggesi and Carlos Simpson Laboratoire J. A. Dieudonné, CNRS UMR 6621 Université de Nice-Sophia Antipolis ...la traduction en langage formalisé ne serait plus qu'un exercise de patience (sans doutes fort pénible). -Nicolas Bourbaki Hanc marginis exiguitas non caperet. -Pierre de Fermat We feel that this context has now changed. For a long time, "mathematics" and "computer science" have designated widely separated disciplines, overlapping only in areas which were considered "fringe" on either side. This was not really a historical view since Von Neumann, Turing and others were mathematicians who set off into the world of computers. We are now entering a time of reconvergence which has all kinds of implications. A prominent one is the increasing reality of computer proof verification as applied to standard mathematical work. This has been under development for quite a while, but just now it is becoming realistic to imagine applying it to a wide array of mathematical situations. The idea is to write mathematical documents in a language such that the mathematical accuracy is then verified by a computer program. This should be compared with other different but related utilization of the computer:
