Practical Information

  • Getting to Göttingen: Göttingen is connected by train to many major cities in Germany. The train station in Göttingen is located immediately to the west of the Altstadt (old town center). Taxis are located behind the train station outside the exit closest to Gates 10/11.
  • Getting around Göttingen: Most destinations can be reached by foot from the hotels and the conference venue. The Göttingen bus system is run by the GöVB, see maps and schedules here. Bus Lines #3, #4 and #5 connect Hotel Novostar and Hotel Leine with the Math Institute area. Guests in Novostar should access the bus at the Gotteslager stop (located outside of the hotel) while guests in Leine should access the bus at the Posthof stop (also a short walk along the main street from the hotel). If taking the #3 and #5, all guests should deboard the bus at Kornmarkt stop (near the intersection of Kornmarkt and Gronerstr.) from there it is a short walk down Nikolaistr. to the Math Institute. If taking the #4, guests should deboard at the Nikolaistr. stop and walk south along Nikolaistr. to the Math Institute. The bus fare is 2 euros per trip. Tickets are available for purchase from the driver.
  • Conference venue and Hotels: All talks will take place in the Mathematisches Institut Georg-August-Universitiät Göttingen. The conference dinner will take place at the Rathauskeller (Bullerjahn). See an interactive map with the hotels and conference venue.
  • Other points of interest: Many of Göttingen's attractions and restaurants lie within the Altstadt, see an interactive map with a selection of different dinning options.

Registration

  • In order to reimburse travel expenses original tickets are needed. If tickets are needed for the journey back, we will first make a copy of them while you are here. You can send the originals to us when you are back home.
  • The registration deadline is extended to October 15th. Please contact Frau Rebecca Willhardt, +49 (0)551 39 7691 for registration. Limited funds are available, in particular for phd students and postdocs. If you wish to be covered (lodging/travel) please indicate it in the registration.
  • Bookings of hotel rooms should be coordinated by Ms Willhardt.
  • Please notice that the registration fee for all participants amounts to 20 Euro. You will pay it at the beginning of the conference.
