A Series of Lectures

Lecturer:  Prof. Dr. Claus M. Ringel
        (Universität Bielefeld, Bielefeld, Germany)
Title:  Foundation of the representation theory of finite dimensional algebras

The lectures will concentrate on quite old, but also very new investigations concerning the Brauer-Thrall conjectures, outlining considerations which complement the usual Auslander-Reiten methods. In particular, I will focus the attention to the Gabriel-Roiter measure which was introduced (as "Roiter measure") by Gabriel in order to make explicit the combinatorial scheme of Roiter's proof of the first Brauer-Thrall conjecture. This proof which was intended just for categories of bounded representation type gives a lot of insight for artin algebras of arbitrary representation type.
