Dieses Buch will dem Leser eine Einfuhrung in wichtige Techniken und Methoden der heutigen reellen Algebra und Geometrie vermitteln. An Voraussetzungen werden dabei nur Grundkenntnisse der Algebra erwartet, so dass das Buch fur Studenten mittlerer Semester geeignet ist.Das erste Kapitel enthalt zunachst grundlegende Fakten uber angeordnete Korper und ihre reellen Abschlusse und behandelt dann verschiedene Methoden zur Bestimmung der Anzahl reeller Nullstellen von Polynomen. Das zweite Kapitel befasst sich mit reellen Stellen und gipfelt in Artins Losung des 17. Hilbertschen Problems. Kapitel...

This volume is a sequel to "Manis Valuation and Prufer Extensions I," LNM1791. The Prufer extensions of a commutative ring A are roughly those commutative ring extensions R / A, where commutative algebra is governed by Manis valuations on R with integral values on A. These valuations then turn out to belong to the particularly amenable subclass of PM (=Prufer-Manis) valuations. While in Volume I Prufer extensions in general and individual PM valuations were studied, now the focus is on families of PM valuations. One highlight is the presentation of a very general and deep approximation...
