Sommario/riassunto |
|
Torsors, also known as principal bundles or principal homogeneous spaces, are ubiquitous in mathematics. The purpose of this book is to present expository lecture notes and cutting-edge research papers on the theory and applications of torsors and étale homotopy, all written from different perspectives by leading experts. Part one of the book contains lecture notes on recent uses of torsors in geometric invariant theory and representation theory, plus an introduction to the étale homotopy theory of Artin and Mazur. Part two of the book features a milestone paper on the étale homotopy approach to the arithmetic of rational points. Furthermore, the reader will find a collection of research articles on algebraic groups and homogeneous spaces, rational and K3 surfaces, geometric invariant theory, rational points, descent and the Brauer-Manin obstruction. Together, these give a state-of-the-art view of a broad area at the crossroads of number theory and algebraic geometry. |

Sommario/riassunto |
|
As the author says, this history, published a year before the outbreak of the Great War, has been written for the soldiers of the battery, past, present and future. It is written in the form of a yearly diary with the year in the left margin, opposite the text describing events of that year. Some entries are very thin, a couple of lines, but other years have a more detailed story to tell - 1808/09 Corunna, 1855 the Crimea, and 1899-1901 the S. African War where the years are divided into mon... |
