This book offers a systematic and comprehensive presentation of the concepts of a spin manifold, spinor fields, Dirac operators, and A-genera, which, over the last two decades, have come to play a significant role in many areas of modern mathematics. Since the deeper applications of these ideas require various general forms of the Atiyah-Singer Index Theorem, the theorems and t...(展开全部)

One night in October when he was ten years old, Tyler Dupree stood in his back yard and watched the stars go out. They all flared into brilliance at once, then disappeared, replaced by a flat, empty black barrier. He and his best friends, Jason and Diane Lawton, had seen what became known as the Big Blackout. It would shape their lives. The effect is worldwide. The sun is now a...(展开全部)

What makes success in major sales? How do some salespeople consistently outsell their competition? Why do techniques like closing work in small sales but fail in larger ones? How can salespeople dramatically increase their sales volume from major accounts? Now you can find answers to all these questions with the SPIN strategy.

All atomic particles have a particular "spin," analogous to the rotation of the Earth about its axis. Simple as spin may sound, the quantum mechanical reality underlying it is complex and still poorly understood. Yet this mysterious quality and the statistics associated with it have vast practical importance to topics as wide-ranging as the stability of atoms and stars and magn...(展开全部)

This volume introduces techniques and theorems of Riemannian geometry, and opens the way to advanced topics. The text combines the geometric parts of Riemannian geometry with analytic aspects of the theory, and reviews recent research. The updated second edition includes a new coordinate-free formula that is easily remembered (the Koszul formula in disguise); an expanded number...(展开全部)

A complete, self-contained introduction to a powerful and resurging mathematical discipline . Combinatorial Geometry presents and explains with complete proofs some of the most important results and methods of this relatively young mathematical discipline, started by Minkowski, Fejes Toth, Rogers, and Erd???s. Nearly half the results presented in this book were discovered over ...(展开全部)

In Euclidean geometry, constructions are made with ruler and compass. Projective geometry is simpler: its constructions require only a ruler. In projective geometry one never measures anything, instead, one relates one set of points to another by a projectivity. The first two chapters of this book introduce the important concepts of the subject and provide the logical foundatio...(展开全部)
