The first section gives a rapid introduction to the subject matter of the seminar. In particular, readers will encounter many notions and constructions, which will be defined and developed only in later sections. It is not expected that everything is to be understood in the first reading. The second section, 1.2, is a more leisurely (or, a less rapid) discussion of some of the basic theory of group algebras, while the last one, Section 1.3, is an introduction to triangulated categories.
