Hotel: Due to limited availability, most of you have been spread over two hotels
- Teneo Apparthotel Talence Centre (Google maps). This is 10 minutes walk away from the university, and next to tram B, stop "Talence centre Forum".
- Appart'hotel Victoria Garden (Google maps). This is close to Tram B, stop "Bergonié". Taking the tram, you will need 20/25 minutes to reach the university from the hotel.
Wednesday restaurant: 19h15 at Le café français (Google maps), next to Tram B, stop "Hôtel de ville".
Program
There will be three talks in the mornings and free afternoons for discussions in smaller groups (informal talks, discussions, programming sessions, ...). A pad is available to organize the afternoonr sessions.
Rooms: the conference room, room 1 and room 109 are located on the first floor of the Institut de Mathématiques. Rooms 285 and 286 are on the second floor, and rooms 385 and 386 are on the third floor. (Hand-made map of the building)
