Mathematical Institute of the University of Bonn

Seminar on Derived Categories

Dr. Olaf Schnürer.

Time: Thursday, 16.15-18.00
Location: Seminar room N0.008, Mathematik-Zentrum, Endenicher Allee 60.

The aim of this seminar is to become familiar with triangulated and derived categories and derived functors. Many of the results we discuss are used at the end to understand Keller's proof of Rickard's Morita theorem.

Please prepare your talk early on so that we can discuss it at the latest one week before you give it, for example after the previous talk. Please provide detailed proofs rather than sketches (as far as possible; if needed, you can have more time).
