The workshop is devoted to the presentation of examples of the strange behaviour of some artin algebras of global dimension 2, to general problems where already the restriction to dimension 2 is open, and to proposals how a structure theory of these artin algebras and their module categories may look like.
The present schedule includes an overview on the difficulties of projective dimension 2 by Dieter Happel, and lectures by Idun Reiten, Steffen Oppermann, Winfried Bruns, Sefi Ladkani, and Helmut Lenzing.
Anyone interested in the subject is invited to participate. Short (or longer) contributions are very well-come, please contact C.M.Ringel (firstname.lastname@example.org). Financial support can be provided by the CRC 701, Bielefeld, please contact C.M.Ringel (email@example.com).
If you like to participate, we would appreciate that you send a short message to firstname.lastname@example.org. Please indicate whether you will join the dinner.
The aim of the workshop is to collect (and make available) as much information and questions as possible.
Anyone is invited to provide suitable
material on the topic,
in the same way as it was done at several previous Bielefeld
Since the workshop has been announced on a very short notice, we cannot expect too many visitors from abroad, thus there is been the proposal that it may be used as a preparation for a slightly larger meeting early next year (either in Bielefeld or as part of the Bonn activities).
