Knots and Links

Author: Dale Rolfsen
Publisher: American Mathematical Soc.
ISBN: 0821834363
Category : Mathematics
Languages : en
Pages : 458

Book Description
Rolfsen's beautiful book on knots and links can be read by anyone, from beginner to expert, who wants to learn about knot theory. Beginners find an inviting introduction to the elements of topology, emphasizing the tools needed for understanding knots, the fundamental group and van Kampen's theorem, for example, which are then applied to concrete problems, such as computing knot groups. For experts, Rolfsen explains advanced topics, such as the connections between knot theory and surgery and how they are useful to understanding three-manifolds. Besides providing a guide to understanding knot theory, the book offers 'practical' training. After reading it, you will be able to do many things: compute presentations of knot groups, Alexander polynomials, and other invariants; perform surgery on three-manifolds; and visualize knots and their complements.It is characterized by its hands-on approach and emphasis on a visual, geometric understanding. Rolfsen offers invaluable insight and strikes a perfect balance between giving technical details and offering informal explanations. The illustrations are superb, and a wealth of examples are included. Now back in print by the AMS, the book is still a standard reference in knot theory. It is written in a remarkable style that makes it useful for both beginners and researchers. Particularly noteworthy is the table of knots and links at the end. This volume is an excellent introduction to the topic and is suitable as a textbook for a course in knot theory or 3-manifolds. Other key books of interest on this topic available from the AMS are ""The Shoelace Book: A Mathematical Guide to the Best (and Worst) Ways to Lace your Shoes"" and ""The Knot Book.""

Book Description
Research in mathematics is much more than solving puzzles, but most people will agree that solving puzzles is not just fun: it helps focus the mind and increases one's armory of techniques for doing mathematics. Mathematical Puzzles makes this connection explicit by isolating important mathematical methods, then using them to solve puzzles and prove a theorem. Features A collection of the world’s best mathematical puzzles Each chapter features a technique for solving mathematical puzzles, examples, and finally a genuine theorem of mathematics that features that technique in its proof Puzzles that are entertaining, mystifying, paradoxical, and satisfying; they are not just exercises or contest problems.

Reforming Federal Land Management

Author: Allan K. Fitzsimmons
Publisher: Rowman & Littlefield
ISBN: 1442215968
Category : Law
Languages : en
Pages : 189

Book Description
For over a century, American have created laws, processes, objectives, priorities, and rules for federal land management that often conflict with each other. We now have inconsistent laws, unclear priorities, procedural mazes, and an antiquated bureaucratic structure. The result is a loss of public benefits and undesirable impact on natural resources. The author argues for major changes and offers new ideas for how those changes can be accomplished.

The Gordian Knot

Author: W. Russell Neuman
Publisher: MIT Press
ISBN: 9780262263917
Category : Technology & Engineering
Languages : en
Pages : 350

Book Description
Veterans of the high-definition TV wars of the 1980s, the authors, social scientists as well as technologists, came to see themselves as "chroniclers and students of an intriguing and serious techno-economic conflict." Why, they asked, did so few understand the rules of the game? In a broad account accessible to generalist and specialist alike, they address the current national debate about the development of a national information infrastructure, locating the debate in a broad historical narrative that illuminates how we got here and where we may be going, and outlining a bold vision of an open communications infrastructure that will cut through the political gridlock that threatens this "information highway."Technical change the authors argue is creating a new paradigm that fits neither the free market nor regulatory control models currently in play. They detail what is wrong with the political process of the national information infrastructure policy-making and assess how different media systems (telecommunications, radio, television broadcasting,) were originally established, spelling out the technological assumptions and organizational interests on which they were based and showing why the old policy models are now breaking down. The new digital networks are not analogous to railways and highways or their electronic forebears in telephony and broadcasting; they are inherently unfriendly to centralized control of any sort, so the old traditions of common carriage and public trustee regulation and regulatory gamesmanship no longer apply. The authors' technological and historical analysis leads logically toward a policy proposal for a reformed regulatory structure that builds and protects meaningful competition, but that abandons its role as arbiter of tariffs and definer of public service and public interest.
