Scientific Programme

Invited talks (titles in italics) have 35 minute slots (T35) and contributed talks 25 minute slots (T25). In both cases at least 5 minutes is reserved for questions and discussion. (Exact times will be added in due course.) Posters will hang in the room immediately in front of the lecture room where we take coffee, and can be viewed during the coffee and lunch breaks. The maximum size of the posters is 125 cm x 150 cm. Discussion sessions are for discussing any more substantial issues which arise.
