This book describes various approaches to the Inverse Galois Problem, a classical unsolved problem of mathematics posed by Hilbert at the beginning of the century. It brings together ideas from group theory, algebraic geometry and number theory, topology, and analysis. Assuming only elementary algebra and complex analysis, the author develops the necessary background from topology, Riemann surface theory and number theory. The first part of the book is quite elementary, and leads up to the basic rigidity criteria for the realization of groups as Galois groups. The second part presents more...

Galois theory is a central part of algebra, dealing with symmetries between solutions of algebraic equations in one variable. This collection of papers brings together articles from some of the world's leading experts in this field. Topics center around the Inverse Galois Problem, comprising the full range of methods and approaches in this area, making this an invaluable resource for all those whose research involves Galois theory.

Im Mittelpunkt des Buchs steht der Begriff des Gleichungssystems, wobei neben linearen Gleichungssystemen auch solche von linearen Differentialgleichungen (und sogar nicht-lineare algebraische Gleichungssysteme) betrachtet werden. Alle Grundbegriffe der Linearen Algebra werden sofort durch die Anwendung auf solche Gleichungssysteme motiviert. Dadurch wird der Aufbau der Linearen Algebra und der Sinn der eingefuhrten Begriffe fur den Anfanger wesentlich verstandlicher, ohne die geringsten Abstriche bei der mathematischen Exaktheit vornehmen zu mussen.
