Book Synopsis Degrees of Unsolvability by : Manuel Lerman
Download or read book Degrees of Unsolvability written by Manuel Lerman and published by Cambridge University Press. This book was released on 2017-04-06 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since their inception, the Perspectives in Logic and Lecture Notes in Logic series have published seminal works by leading logicians. Many of the original books in the series have been unavailable for years, but they are now in print once again. In this volume, the eleventh publication in the Perspectives in Logic series, Manuel Lerman presents a systematic study of the interaction between local and global degree theory. He introduces the reader to the fascinating combinatorial methods of recursion theory while simultaneously showing how to use these methods to prove global theorems about degrees. The intended reader will have already taken a graduate-level course in recursion theory, but this book will also be accessible to those with some background in mathematical logic and a feeling for computability. It will prove a key reference to enable readers to easily locate facts about degrees and it will direct them to further results.
Book Synopsis Degrees of Unsolvability by : R. L. Epstein
Download or read book Degrees of Unsolvability written by R. L. Epstein and published by Springer. This book was released on 2006-11-15 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex interactions of economic, technological, political, and cultural factors have fed the rise of criminal networks worldwide. At the same time, global illegal activities depend on a world of social realities to function. Organized Crime moves beyond traditional concepts of "evil forces" corrupting their host societies, instead analyzing local, national, and international manifestations of organized crime in the situational contexts that aid in its development. The contributors provide up-to-date understanding of various aspects of organized crime, in both classic areas of research (drugs, sex trafficking, labor racketeering) and emerging areas of interest (diamond smuggling, money laundering, eco-crime), in locales as varied as Italy, Quebec, the Sinai, Bulgaria, and the world's tropical rain forests. Topics are explored from a variety of perspectives, including sociology, criminology, political science, and anthropology, giving this book empirical breadth and depth rarely seen in the literature. A sampling of the topics: Symbolic and economic meanings of crime to cultures. The symbiotic relationships between legitimate and criminal activities. Ethical dilemmas of legitimate businesses with criminal clients. Marketing, problem-solving, recruitment: organizational models of criminal enterprises. Innovative law enforcement/administrative strategies for containing and preventing crime in the U.S. and across Europe. Scholars and researchers of organized crime as well as advanced students of criminology will welcome Organized Crime for coverage that is wide-ranging, comparative, and specific enough to match their interests

Book Synopsis Handbook of Computability Theory by : E.R. Griffor
Download or read book Handbook of Computability Theory written by E.R. Griffor and published by Elsevier. This book was released on 1999-10-01 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this volume all have their own level of presentation. The topics have been chosen based on the active research interest associated with them. Since the interest in some topics is older than that in others, some presentations contain fundamental definitions and basic results while others relate very little of the elementary theory behind them and aim directly toward an exposition of advanced results. Presentations of the latter sort are in some cases restricted to a short survey of recent results (due to the complexity of the methods and proofs themselves). Hence the variation in level of presentation from chapter to chapter only reflects the conceptual situation itself. One example of this is the collective efforts to develop an acceptable theory of computation on the real numbers. The last two decades has seen at least two new definitions of effective operations on the real numbers.

Book Synopsis Turing Computability by : Robert I. Soare
Download or read book Turing Computability written by Robert I. Soare and published by Springer. This book was released on 2016-06-20 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turing's famous 1936 paper introduced a formal definition of a computing machine, a Turing machine. This model led to both the development of actual computers and to computability theory, the study of what machines can and cannot compute. This book presents classical computability theory from Turing and Post to current results and methods, and their use in studying the information content of algebraic structures, models, and their relation to Peano arithmetic. The author presents the subject as an art to be practiced, and an art in the aesthetic sense of inherent beauty which all mathematicians recognize in their subject. Part I gives a thorough development of the foundations of computability, from the definition of Turing machines up to finite injury priority arguments. Key topics include relative computability, and computably enumerable sets, those which can be effectively listed but not necessarily effectively decided, such as the theorems of Peano arithmetic. Part II includes the study of computably open and closed sets of reals and basis and nonbasis theorems for effectively closed sets. Part III covers minimal Turing degrees. Part IV is an introduction to games and their use in proving theorems. Finally, Part V offers a short history of computability theory. The author has honed the content over decades according to feedback from students, lecturers, and researchers around the world. Most chapters include exercises, and the material is carefully structured according to importance and difficulty. The book is suitable for advanced undergraduate and graduate students in computer science and mathematics and researchers engaged with computability and mathematical logic.

Book Synopsis Computability in Context by : S Barry Cooper
Download or read book Computability in Context written by S Barry Cooper and published by World Scientific. This book was released on 2011-02-25 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computability has played a crucial role in mathematics and computer science, leading to the discovery, understanding and classification of decidable/undecidable problems, paving the way for the modern computer era, and affecting deeply our view of the world. Recent new paradigms of computation, based on biological and physical models, address in a radically new way questions of efficiency and challenge assumptions about the so-called Turing barrier. This volume addresses various aspects of the ways computability and theoretical computer science enable scientists and philosophers to deal with mathematical and real-world issues, covering problems related to logic, mathematics, physical processes, real computation and learning theory. At the same time it will focus on different ways in which computability emerges from the real world, and how this affects our way of thinking about everyday computational issues.
