Cubic forms : algebra geometry arithmetic Since this book was first published in English there has been important progress in a number of related topics. The class of algebraic varieties close to the rational ones has crystallized as a natural domain for the methods developed and expounded in this volume. For this revised edition the original text has been left intact (except for a few corrections) and has been brought up to date by the addition of an Appendix and recent references. The Appendix sketches some of the most essential new results constructions and ideas including the solutions of the Luroth and Zariski problems the th Front Cover; Cubic Forms: Algebra Geometry Arithmetic; Copyright Page; PREFACE TO THE SECOND EDITION; CONTENTS; INSTRUCTIONS TO THE READER; INTRODUCTION; CHAPTER I.
