How to get to the conference site
The conference will take place at the
Orsay campus of
the University Paris-Sud situated in the Chevreuse Valley
about 20 km to the south west from Paris (
location on the map). It is close to the
station "Orsay-Ville" of the
RER B line (use the
interactive plan of the public transportation; the RER B is the thick blue line from the north to the south). Between Paris and Orsay, there is a train every 10-15 minutes. The line RER B has several branches with various destinations, so please
make you sure that your train stops in "Orsay-Ville". Please note that the Charles de Gaulle airport and the railway stations Gare du Nord and Massy TGV are on the same line. The Orly airport is linked by Orlyval to the station Antony which is on the same line too.
- If you arrive from Paris, the campus is on the right-hand side. Find the building 425 (Mathematics department). You may use the campus map (pdf) and the annotated Google map. In the building, look for the lecture hall 029 (petit amphi) on the ground floor.
- If you are staying at the Hôtel d'Orsay or Residhome Bures (see below), simply walk to the department. Use the campus map (pdf) and the annotated Google map.
The official address of the Orsay campus: 15 rue Georges Clemenceau, 91400 Orsay.
Tickets
If you use RER B trains outside Paris, you need a special ticket Origin-Destination. The standard parisian ticket "T+" is not valid. The ticket "from A to B" is also valid for "from B to A". The ticket "from A to Paris" is valid from any station inside Paris to the station A (and the other way round).
Accommodation
The participants are kindly asked to book their accommodation by themselves. If you never visited Orsay before, please read the information carefully and study the maps attached before you book a room.
- There are two hotels at a walking distance from the department (800 meters, 10 minute walk): Hôtel d'Orsay (the recommended one, close to the station RER B "Le Guichet") and Residhome Bures (station RER B "Bures-sur-Yvette"). The both hotels are marked on the campus map (pdf) and on the annotated Google map.
- There are another two hotels (reasonably priced), Hôtel Le Village and Hôtel Le Coupières, in Gif-sur-Yvette (another village close to the campus). It is not exactly at a walking distance (ca. 3 km),
but the commuting is quite easy (three stations from Gif-sur-Yvette to Orsay-Ville by RER B, 5 minutes by train, the ticket costs 1,90€ as of May 2015). See the annotated Google map.
- If you prefer to stay in Paris, it is advised to take a hotel which is close to a station of the RER B line (i.e. Cité Universitaire, Denfert-Rochereau, Port-Royal, Luxembourg). The trajectory between these stations and Orsay-Ville takes about 30 minutes (in general, one should count on 1 hour door-to-door). Some hotels in Paris which are used frequently by the visitors of parisian universities: SolarHotel, Hôtel Pierre Nicole, Hôtel Sunny, Hôtel de Senlis, Hôtel de la Tour, Hôtel du Brésil, Hôtel du Parc Montsouris, Hôtel du Lion, Hôtel Cluny-La Sorbonne. The one-way ticket from Paris to Orsay-Ville costs 4,35€ (May 2015).
- Please note that the services like booking.com may offer better prices.
Lunch, dinner
The lunches will be organised at the campus. If you stay close to the campus (Orsay/Bures/Gif), you may go for a dinner to one of the restaurants in the central part of the respective villages (please note that most places open for dinner around 20:00). In the same area you may find other services (banks, shops, restaurants, bars and so on). Please use the
annotated Google map.
