Operator theory & boundary value problems, May 25-27, 2011, Orsay

Updated on 30 May 2011

The talks will take place the conference room "Salle de conferences Edgar Lederer" of the building 430 at the Orsay Campus (campus map; it is just near the central university library); the room is in the ground floor, just on the left after the entrance (the most part of the building is used by the chemistry department, so do not be afraid of the equipment you may meet at the doors). The registration and the coffee breaks will be in the common room of the mathematics department (room 107) of the same building; the same room can be used for discussions. It is in the first floor, take the stairs in front of the entrance, then follow the pointers "Mathematiques". The conference cocktail will take place in the tea room (salle de thé 1er étage) in the first floor of the building 425 (the main building of the mathematics department).

Check the conference webpage: http://orsay2011.info for all information (in particular, directions, abstracts, accommodation).

Equipment available for the talks: a video projector with a laptop and a slide projector (both in the landscape orientation), a whiteboard (1,3 meter * 4,5 meters), see photo below. You can come with a PDF-presentation on a USB-stick (or send it in advance to konstantin.pankrashkin@math.u-psud.fr).
