Short talks

Other useful information

To get to the workshop:

Please read carefully the following explanations and print the maps.

The "Paris Rive Gauche" campus of University Paris 7 "Denis Diderot" is in the south-east of Paris (XIIIth district), between the National Library and the ringroad. It can be accessed from the station "Bibliothèque François-Mitterrand" of RER C or subway line 14, by buses 89, 62, 64, 325, and by the "velib" bicycles (see map of stations).

The Condorcet building is close to the Seine river and has a distinct orange color. From subway line 14, RER C or bus 89 (arrêt "Bibliotèque François Mitterrand") go to the Seine by walking downhill, then turn right. See the map of the district and the detailed map of the building. On these maps, green dots label the building entrances.

Caution: these streets are new. Some commercial maps or GPS systems have not yet incorporated them. Watt street, which is almost identical to Alice Domon and Léonie Duquet, is normally always indicated.

Caution again: this building is subdivided into two subunits, Condorcet A and Condorcet B, which are connected only at the ground floor (as well as a footbridge at 4th floor and another one at 6th floor).

Caution again: at night it is only possible to leave this building through the guarded door on 10 rue Alice Domon and Léonie Duquet, close to the river.

The workshop will be held in room 646A ("Mondrian") of the laboratory Matière et Systèmes Complexes (MSC), on the 6th floor of bâtiment Condorcet A.
