General
Comments:
The
workshop – like its preceding ones – is organized on an informal and highly
interactive basis. All participants are invited to actively contribute to the
success of the event. This shall be achieved by
1. the
working papers of the presentations can be downloaded from the workshop
web-site. All participants are expected to read the papers, so that the
focus of the presentation can be less introductory and focus on the essential
and hard problems.
2. There
are break-out sessions, where the whole group splits and discusses in depth
given specific topics with a small number of people. The results of the
discussions are reported back to the whole group. Tentative topics are given in
the program, however, this is still open to be finalized during the workshop.
