Knots and Crosses introduces gifted mystery novelist Ian Rankin, a fascinating locale and the most compellingly complex detective hero at work today. Inspector John Rebus: His city is being terrorized by a baffling series of murders...and he's tied to a maniac by an invisible knot of blood. Once John Rebus served in Britain's elite SAS. Now he's an Edinburgh cop who hides from his memories, misses promotions and ignores a series of crank letters. But as the ghoulish killings mount and the tabloid headlines scream, Inspector Rebus cannot stop the feverish shrieks from within his own mind. Because he isn't just one cop trying to catch a killer, he's the man who's got all the pieces to the puzzle....

For the first time in the US, this timeless cat-and-mouse classic from the Edgar Award-winning "genius" examines political tensions in an era of espionage (Lee Child, bestselling author of the Jack Reacher series). In Europe, the Americans are pulling out their troops in a tide of isolationism. Britain, torn between loyalties to America and the continent, is caught in the middle. Across the pond, a space shuttle crashes on landing, killing all but one of the crew on board: A British citizen named Mike Dreyfuss, who will become vilified by the US press and protesters. Halfway across the world, at English ground control headquarters, Martin Hepton watches with dismay as they lose contact with the most advanced satellite in Europe. When a colleague who suspects something strange disappears, Hepton realizes there is much more at stake than anyone knows -- and many more people on his trail than he can possibly evade . . .

Knots are familiar objects. Yet the mathematical theory of knots quickly leads to deep results in topology and geometry. This work offers an introduction to this theory, starting with our understanding of knots. It presents the applications of knot theory to modern chemistry, biology and physics.

Just this once . . . Please let me get away with it just this once . . . Tobey wants a better life - for him and his girlfriend Callie Rose. He wants nothing to do with the gangs that rule the world he lives in. But when he's offered the chance to earn some money just for making a few 'deliveries', just this once, would it hurt to say 'yes'? One small decision can change everything . . . The fourth novel in Malorie Blackman's powerful Noughts & Crosses sequence.

The physical properties of knotted and linked configurations in space have long been of interest to mathematicians. More recently, these properties have become significant to biologists, physicists, and engineers among others. Their depth of importance and breadth of application are now widely appreciated and valuable progress continues to be made each year.This volume presents several contributions from researchers using computers to study problems that would otherwise be intractable. While computations have long been used to analyze problems, formulate conjectures, and search for special structures in knot theory, increased computational power has made them a staple in many facets of the field. The volume also includes contributions concentrating on models researchers use to understand knotting, linking, and entanglement in physical and biological systems. Topics include properties of knot invariants, knot tabulation, studies of hyperbolic structures, knot energies, the exploration of spaces of knots, knotted umbilical cords, studies of knots in DNA and proteins, and the structure of tight knots. Together, the chapters explore four major themes: physical knot theory, knot theory in the life sciences, computational knot theory, and geometric knot theory.

Knot theory is a classical area of low-dimensional topology, directly connected with the theory of three-manifolds and smooth four-manifold topology. In recent years, the subject has undergone transformative changes thanks to its connections with a number of other mathematical disciplines, including gauge theory; representation theory and categorification; contact geometry; and the theory of pseudo-holomorphic curves. Starting from the combinatorial point of view on knots using their grid diagrams, this book serves as an introduction to knot theory, specifically as it relates to some of the above developments. After a brief overview of the background material in the subject, the book gives a self-contained treatment of knot Floer homology from the point of view of grid diagrams. Applications include computations of the unknotting number and slice genus of torus knots (asked first in the 1960s and settled in the 1990s), and tools to study variants of knot theory in the presence of a contact structure. Additional topics are presented to prepare readers for further study in holomorphic methods in low-dimensional topology, especially Heegaard Floer homology. The book could serve as a textbook for an advanced undergraduate or part of a graduate course in knot theory. Standard background material is sketched in the text and the appendices.

LET IT BLEED: Rebus finds himself sucked into an investigation that throws up more questions than answers. Was the Lord Provost's daughter kidnapped or just another runaway? And why on earth is Rebus invited to a clay pigeon shoot at the home of the Scottish Office's Permanent Secretary? Drawn into the machine that is modern Scotland, Rebus confronts the fact that some of his enemies may be beyond justice. BLACK & BLUE: Rebus is juggling four cases trying to nail one killer - and doing it under the scrutiny of an internal inquiry led by a man he's just accused of taking backhanders from Glasgow's Mr Big. Added to that there are TV cameras at his back investigating a miscarriage of justice, making Rebus a criminal in the eyes of millions of viewers. Just one mistake is likely to mean a slow and unpleasant death or, worse still, losing his job. THE HANGING GARDEN: DI John Rebus is on the trail of a WWII war criminal - until the running battle between two rival gangs on the city streets arrives at his door. When his daughter is the victim of a hit-and-run Rebus is forced to acknowledge that there is nothing he wouldn't do to bring down the prime suspect - even if it means cutting a deal with the devil.

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.""

This publication is a compilation of reports on all plant species and varieties that have been called either resistant or tolerant to infestation by the root knot nematode, Heterodera marioni (Cornu) Goodey, (formerly called H. radicola (Greef) Mueller). The purpose is twofold: to bring together all available information on the subject in condensed form for the use of growers, plant breeders, and other investigators, and to establish a basis for the contribution of further data. It must not be assumed that all of the plants listed here are recommended as resistant. They intention is rather to present technical source material, not only useful to those who need practical information on particular plants but also suggestive to future workers.
