LOCATION OF THE WORKSHOP

The workshop takes place at the Université de Lille 1, Salle de Réunion, Bâtiment M2 (first floor), Cité Scientifique, Villeneuve d'Ascq, in the north of France. This lecture hall is located in the main building M2 of the department of mathematics. Some useful links

PARTICIPANTS

You are kindly invited to participate at this meeting. Please let us know if you are interested to join us [preliminary list of participants].

ACCOMODATION AND SOCIAL EVENTS

From december 2003 to december 2004, Lille is european capital of culture. As a consequence, it might be a bit tricky to reserve hotels. Please let us know as fast as possible if you intend to stay in a hotel, either downtown or on the campus, we would be pleased to help you to reserve a room.
Hotels:
We have reserved rooms in the following hotels (all in downtown Lille)
Social events:

SUPPORT FOR THE WORKSHOP

We kindly acknowledge support from the Laboratoire Paul Painlevé UMR 8524 (UST Lille - CNRS) and from the Laboratoire de Mathématiques Pures et Appliquées Joseph Liouville (U Littoral Cote d'Opale).
