SCOPE

The aim of this meeting, the third one after similar meetings in 2000 and 2004, is to bring together people interested in Approximation Theory from France and Belgium, but also from other places.

This meeting also includes a short-course on "discrete minimal energy problems" delivered by E.B. Saff, which is in particular accessible for non-experts and especially for PhD students (pour savoir plus sur comment repartir des points sur une surface voir un article de vulgarisation paru dans Science & Vie, et un article plus mathématique paru dans Notices of the American Mathematics Society (2004)).

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
