The conference will take place in the mathematics department at Cergy-Pontoise University, France.

How to get there (with map): link.   /   Directions pour venir (avec plan) : lien.


Otherwise, follow the following directions:

First, find the RER A and go to Cergy-Prefecture Station.

1) From RER Cergy-Prefecture Station to Hotel Première Classe.

After passing through the unique exit (and entry) which requires your ticket, turn right and go up with escalator on the open air. Then go straight until you pass underneath a modern building. You will be on a square with a fontaine. There you will see Hotel Premiere Classe on your left.


2) From Hotel Première Classe to University (conference building).

Reach the big street in front of the hotel (Avenue des 3 Fontaines), turn right and follow the street. Go down with staircase on the left before a right bend. Follow the big street (Boulevard du Port) until you pass underneath a highway (A15). Go straight ahead and you will see on your right a glassy building (on the left there is a car dealer and then the Hotel Campanile). And it's there! The main entry is located at the very end of the building. It will take you about 10 min to arrive here from the hotel.


3) From RER Cergy-Prefecture Station to Hotel Campanile, Hotel Formule 1 and University (conference building).

After passing through the unique exit (and entry) which requires your ticket, turn left on the Boulevard de l'Oise (do not take the stairs). Walk for about 200m. At the next cross, you can see buildings of the university in front of you: they are not the right ones ! Take the road on the right (Boulevard du Port) and continue straight for about 300m. The road passes under the highway. A little bit further, you can see the Saint-Martin buildings on the right, and on the left a car seller and then the Hotel Campanile (via a staircase going up). Hotel Formule 1 is hidden behind the car seller. It will take you about 10 min to arrive there from the Cergy-Préfecture train station.

You can also take the bus from RER station (at the exit). Find the bus 36 or 44 to Pontoise Canrobert. And get off at the the first bus stop : Plateau St-Martin. The University is nearby and Hotels are across the road (find the staircase).

Première classe is next to the RER train station and 10mn walking distance from the conference location. For Formule 1 and Campanile, this is the converse. Compared to Formule 1, Première classe is better (shower in the room).

The distance from the conference location to the center of Paris (the Chatelet station) is comparable to that from IHES (10mins walk+ 35mins direct RER ride). So you may choose to stay in downtown Paris.
