We suggest talks of 1 hour (time  for  discussion  not included).
The preferred language is English. In case of a German or French talk, at least  transparencies should be in English.
The lecture room is equipped with blackboards, overhead projector and beamer. The idea is to make a presentation for doctoral students from all branches of mathematics. This excludes technical talks. Speakers are asked to present the ideas, problems, results, techniques in an accessible way.
