Real Algebraic Geometry

This book is a systematic treatment of real algebraic geometry. It is carefully and clearly written; it starts with the basic concepts and leads to up-to-date research topics. The present volume is a translation, revision and updating of ERGEBNISSE vol.12, published in French in 1987. Many new developments in this field have been included in this book.

A systematic treatment of real algebraic geometry Carefully and clearly written may serve as a basis for a graduate course Many of the new developments are included in this edition

The present volume is a translation, revision and updating of our book (pub­lished in French) with the title "Géométrie Algébrique Réelle". Since its pub­lication in 1987 the theory has made advances in several directions. There have also been new insights into material already in the French edition. Many of these advances and insights have been incorporated in this English version of the book, so that it may be viewed as being substantially different from the original.
