Extractions: The Pythagorean Theorem In a right triangle, the longest side is called the hypotenuse. The hypotenuse is always the side opposite the right angle. The other two sides are called the legs of the triangle. We usually use the variables a and b to identify the legs and c for the hypotenuse. They are related as follows. In any right triangle, if a and b are the lengths of the legs and c is the length of the hypotenuse, then

A General Conservative Extension Theorem In Process Algebra
A general conservative extension theorem in process algebra. C. VerhoefDepartment of Mathematics and Computing Science, Eindhoven
http://adam.wins.uva.nl/~x/ece/finalifip.html

Extractions: Keywords: Concurrency; Operational Semantics; Algebraic language theory. In the past few years people working in the area of process algebra have started to extend process theories such as CCS, CSP, and ACP with, for instance, real-time or probabilistics. A natural question that arises is whether or not such an extension is somehow related with its subtheory, for instance, whether or not the extension is conservative in some sense. If we add new operators and/or rules to a particular transition system it would be nice to know whether or not provable transitions of a term in the original system are the same as those in the extended system for that term; we will call this property operational conservativity (cf.

http://geosci.uchicago.edu/~gidon/geosci236/fundam/

Extractions: Figure 1: The forward problem (the fundamental theorem of linear algebra). A 's domain is the upper-left space, while its range is the lower-right one. In the domain, A 's row-space is shown in red , while its nullspace in blue . A generic vector comprising both a row-space and a nullspace components is the vector on which A operates, mapping it onto the adjoint space (lower-right). In the latter space, the shown b comprises components from A 's range (column-space) and left nullspace Figure 1 represents the operation of a matrix on a vector (the upper-left space). That is, it shows schematically what happens when an arbitrary vector from 's domain (the space corresponding dimensionally to 's row dimension N ) is mapped by onto the range space (the space corresponding dimensionally to 's column dimension M ). Hence the schematic shows what happens to from the upper-left space as transforms it to the range, the lower-right space. Put differently, this schematic represents the

Site responsible: Prof. Herman Geuvers Site members: The Sub-faculty of Computer Science at the University of Nijmegen hosts a broad experience in logic, formal methods and theorem proving. The Faculty of Mathematics and Computer Science of Eindhoven University of Technology is strong in computer algebra, theorem proving and applying Web technology to mathematics. Nijmegen and Eindhoven have a long history in cooperation on topics related to this FET proposal, notably type theory, theorem proving and combining various computer mathematics applications, especially using OpenMath. This cooperation was mainly taking place between the research groups of Geuvers and Barendregt in Nijmegen and the research group of Cohen in Eindhoven. The research group of Geuvers and Barendregt is part of the EC sponsored Thematic Network ``TYPES'' (IST-1999-29001) and of its ancestor, the EC Working Group ``Types for Proofs and Programs'', which testifies there interest in theorem proving, especially using type theory based theorem provers. The FTA project (Fundamental Theorem of Algebra), started in 1999 and to be finished in 2001, has as its main goal to formalize (in Coq) a large body of undergraduate mathematics (algebra and analysis), culminating in a proof of the fundamental theorem of algebra. The formalization of the mathematics is now finished and the next step is to make the formalization accessible and usable by others, preferably through the World Wide Web.
Computer Algebra Meets Automated Theorem Proving: Integrating Maple And PVS
Computer algebra Meets Automated theorem Proving Integrating Mapleand PVS. Authors. Andrew Adams, Martin Dunstan, Hanne Gottliebsen
http://www.csl.sri.com/users/owre/papers/tphols01/

Extractions: Andrew Adams, Martin Dunstan, Hanne Gottliebsen, Tom Kelsey, Ursula Martin, and Sam Owre We describe an interface between version 6 of the Maple computer algebra system with the PVS automated theorem prover. The interface is designed to allow Maple users access to the robust and checkable proof environment of PVS. We also extend this environment by the provision of a library of proof strategies for use in real analysis. We demonstrate examples using the interface and the real analysis library. These examples provide proofs which are both illustrative and applicable to genuine symbolic computation problems. PDF Sam Owre: owre@csl.sri.com

Selected papers. LNCS 906, Springer Verlag. Abstract We present a general approach for integrating certain mathematical structures in first-order equational theorem provers. More specifically, we consider theorem proving problems specified by sets of first-order clauses that contain the axioms of a commutative ring with a unit element. Associative-commutative superposition forms the deductive core of our method, while a convergent rewrite system for commutative rings provides a starting point for more specialized inferences tailored to the given class of formulas. We adopt ideas from the Gröbner basis method to show that many inferences of the superposition calculus are redundant. This result is obtained by the judicious application of the simplification techniques afforded by convergent rewriting and by a process called symmetrization that embeds inferences between single clauses and ring axioms.

http://www.dcs.gla.ac.uk/provers/stp/0397/steve.html

Extractions: Steve Linton Computer Algebra systems have a number of features that distinguish them from other software systems of similar size and complexity: on the one hand, there is the natural underlying semantics of pure mathematics, on the other hand, many of the algorithms used rely on sophisticated mathematical results for their correctness and may impose conditions on their inputs that go far beyond the scope of normal type checking. Finally, these systems tend to grow over time, and without a formal framework for the precise communication of the functions and restrictions of existing components, this process is inefficient and unsafe. This talk will describe the possible relationships between computer algebra systems and Automated Theorem Proving, and the benefits offered by each, and then outline the work being done in St Andrews on one of them.

Extractions: A mechanized mathematics system (MMS) is a computer environment that is intended to support, improve, and sometimes automate mathematical reasoning and computing. Computer algebra systems and computer theorem proving systems are both examples of MMSs. Each type of MMS has its own strengths and weaknesses. Our objective is develop a new approach to mechanized mathematics that combines the strengths of symbolic algebra systems with those of theorem proving systems to provide a system that is both powerful and sound.
