This must-read text presents the pioneering work of the late Professor Jacob (Jack) T. Schwartz on computational logic and set theory and its application to proof verification techniques, culminating in the ÆtnaNova system, a prototype computer program designed to verify the correctness of mathematical proofs presented in the language of set theory. Topics and features: describes in depth how a specific first-order theory can be exploited to model and carry out reasoning in branches of computer science and mathematics; presents an unique system for automated proof verification in large-scale software systems; integrates important proof-engineering issues, reflecting the goals of large-scale verifiers; includes an appendix showing formalized proofs of ordinals, of various properties of the transitive closure operation, of finite and transfinite induction principles, and of Zorn’s lemma.

'In a short life he accomplished much, and to the roll of great names in the history of his particular studies added his own.' So is described one of the greatest figures of the twentieth century, yet Alan Turing's name was not widely recognised until his contribution to the breaking of the German Enigma code became public in the 1970s. The story of Turing's life fascinates and in the years since his suicide, Turing's reputation has only grown, as his contributions to logic, mathematics, computing, artificial intelligence and computational biology have become better appreciated. To commemorate the centenary of Turing's birth, this republication of his mother's biography is enriched by a new foreword by Martin Davis and a never-before-published memoir by Alan's older brother. The contrast between this memoir and the original biography reveals tensions and sheds new light on Turing's relationship with his family, and on the man himself.

Hughes, Davis, Matthew and Jones: Text and Materials on Housing Law is a collection of housing case law and legislation combined with commentary to enable students fully to understand the often complicated language of the law. It gathers together all the important original materials to which students of housing law will need to have access. Text and Materials on Housing Law Covers housing law topics at undergraduate and postgraduate level Explores the increasingly important area of housing and human rights Deals with housing issues raised by the changing patterns of relationships within society Covers unlawful eviction and the new legislation on homelessnessThe inclusion of procedural material in this work is of great value to housing professionals (local authorities, housing associations, high-street solicitors) and also enhances its usefulness to academics and students by linking the relevant substantive law to a procedural awareness.

Computability, Complexity, and Languages is an introductory text that covers the key areas of computer science, including recursive function theory, formal languages, and automata. It assumes a minimal background in formal mathematics. The book is divided into five parts: Computability, Grammars and Automata, Logic, Complexity, and Unsolvability.

Arnold Palmer: American Hero is the seventh book in our large coffee table book series on the greats in the game. In addition to our definitive history of the Ryder Cup published in conjunction with the PGA of America, we have also published large lavishly produced coffee table books in this format on - Ben Hogan (2), Bobby Jones, Byron Nelson and Jack Nicklaus. The book features wonderfully crafted essays on different aspects of Arnie's life in the front third of the book with game-day coverage of each of his biggest tournaments in the back two-thirds. As with all our books, our book on Arnie sports a real cloth cover with gold foil stamping and a laminated and embossed dust jacket. To achieve the utmost in quality reproduction, the book has been printed in five colors in Italy on some of the finest printing papers available by one of the world's most renown printers. Even the black-and-white photos are color separated to ensure the utmost in fidelity. Once again, we've assembled an all-star cast of essayists, each writing on different aspects of Arnie's life, but for this book we assembled 21 featured essayists in all, instead of the usual five or six. There were just so many fascinating - and wholly unknown - facets to Arnie's life that just begged coverage. It seems that every time we would investigate one aspect of his life, we'd find two more to delve into. The further we looked, we'd add another essay or two as the book just kept getting bigger and bigger - and we do believe - better and better. Consider a sampling of the featured essayists - Marino Parascenzo (former president of the Golf Writers Association of America), Doc Giffen (Arnold's right-hand man since the mid 1960s), Jaime Diaz (Golf Channel), John Hopkins (The Times of London), Dan Hicks (who covered Arnie's tournament for NBC for over 25 years), Ron Green, Jr. (Global Golf Post), Charlie Mechem (former LPGA Commissioner), Ron Sirak (the Associated Press and Golf Digest), Jay Monahan (PGA TOUR Commissioner), Kelly Tilghman (Golf Channel), Adam Schupak (Golf World), Peter Jacobsen (PGA TOUR and NBC), Nancy Lopez (LPGA and World Golf Hall of Fame) and numerous others. Even Arnie's close friend Gary Player crafted a very personal forward with much new and revelatory information about their relationship - you'll laugh, you'll smile and you may even get a bit teary. It's certainly an All Star cast of contributors. As with our earlier coffee table books on the greats of the game, the back two-thirds of the book features extensive take-outs with numerous large photos - along with the game day stories on every significant event in Arnie's life - all the big wins as well as the many heartbreaking close calls too. Significantly, also included are several multi-page instructional gatefold spreads throughout the book including an analysis of Arnie's full swing by noted golf instructor Jim McLean, an analysis of his putting by putting-guru Brad Faxon and a large gatefold - folding out to almost six feet - featuring Arnie's seven Ryder Cup wins. There's even a gatefold depicting each of Tiger's eight wins at Arnie's own PGA TOUR event at Bay Hill. Without doubt, it certainly is a book of the very highest caliber.

The collapse of the Soviet Union has seen the emergence of its unprecedentedly comprehensive global secret military mapping project and the commercial availability of a vast number of detailed topographic maps and city plans at several scales. This thesis provides an in-depth examination of the series of over 2,000 large-scale city plans produced in secret by the Military Topographic Directorate (??????? ??????????????? ??????????) of the General Staff between the end of the Second World War and the collapse of the USSR in 1991. After positioning the series in its historical context, the nature and content of the plans are examined in detail. A poststructuralist perspective introduces possibilities to utilise and apply the maps in new contexts, which this thesis facilitates by providing a systematic, empirical analysis of the Soviet map symbology at 1:10,000 and 1:25,000, using new translations of production manuals and a sample of the city plans. A comparative analysis with the current OpenStreetMap symbology indicates scope for Soviet mapping to be used as a valuable supplementary topographic resource in a variety of existing and future global mapping initiatives, including humanitarian crisis mapping. This leads to a conclusion that the relevance and value of Soviet military maps endure in modern applications, both as a source of data and as a means of overcoming contemporary cartographic challenges relating to symbology, design and the handling of large datasets.

Trixie Treat is still only fifteen years old. But suddenly, all kinds of interesting people are trying to kill her. People inside her school. People outside her school. And one particularly large being who inhabits its own substantial space in our galaxy, but who isn't too keen on following the rules of the "game" Trixie is forced to play. The stars have set a Task for Trixie. Evidently, not everyone wants her to complete it. As the story accelerates towards its cataclysmic conclusion, the friends helping her are increasingly in danger. Her family is in danger (the intervention of highly-paid assassins being a distinct possibility). And if she can't deliver when it counts, a whole lot of other people are in danger too. Plus, she has a life of her own to lead. And the fact that she has to spend all this time on Conflict, Plotting and just generally Staying-Alive is really, really beginning to annoy her!!

Trixie Treat is fifteen years old and realises that she is privileged. Big house. Posh school. Nice family. Oh ... and the small matter of being able to hear the stars talking; although she has never told anyone about this and can't actually understand what the astral giants are saying - yet. When she finds out, she's going to be mildly horrified. Because she's also going to discover who she really is, what she really has to do, who she's going up against - and what's at stake if she fails.

This introduction to functional analysis is based on the lecture notes of Martin Davis, a distinguished professor of mathematics. The treatment demonstrates the essential unity of mathematics without assuming more background than can be expected of advanced undergraduates and graduate students majoring in mathematics. A self-contained exposition of Gelfand's proof of Wiener's theorem, this volume explores set theoretic preliminaries, normed linear spaces and algebras, functions on Banach spaces, homomorphisms on normed linear spaces, and analytic functions into a Banach space. Numerous problems appear throughout the book.

Geared toward upper-level undergraduates and graduate students, this text assumes no knowledge of mathematical logic; it develops the key techniques of nonstandard analysis at the outset from a single, powerful construction. Then, beginning with a nonstandard construction of the real number system, it leads students thorough the basic topics of elementary real analysis, topological spaces, and Hilbert space. Important subjects include nonstandard treatments of equicontinuity, nonmeasurable sets, and the existence of Haar measure. The focus on compact operators on a Hilbert space includes the Bernstein-Robinson theorem on invariant subspaces, which was first proved with nonstandard methods. 1977 ed.

"A valuable collection both for original source material as well as historical formulations of current problems."--"The Review of Metaphysics"Much more than a mere collection of papers . . . a valuable addition to the literature."--"Mathematics of Computation An anthology of fundamental papers on undecidability and unsolvability by major figures in the field, this classic reference opens with Godel's landmark 1931 paper demonstrating that systems of logic cannot admit proofs of all true assertions of arithmetic. Subsequent papers by Godel, Church, Turing, and Post single out the class of recursive functions as computable by finite algorithms. Additional papers by Church, Turing, and Post cover unsolvable problems from the theory of abstract computing machines, mathematical logic, and algebra, and material by Kleene and Post includes initiation of the classification theory of unsolvable problems. Suitable for graduate and undergraduate courses. 1965 ed.
