Das Werk ist eine Einführung in die Charaktertheorie endlicher Gruppen, die zusammen mit der Darstellungstheorie einen wichtigen Bestandteil bei der Untersuchung der Struktur endlicher Gruppen bildet

The aim of the Expositions is to present new and important developments in pure and applied mathematics. Well established in the community over more than two decades, the series offers a large library of mathematical works, including several important classics.

The volumes supply thorough and detailed expositions of the methods and ideas essential to the topics in question. In addition, they convey their relationships to other parts of mathematics. The series is addressed to advanced readers interested in a thorough study of the subject.
