Some in­for­ma­ti­on you may find use­ful

  • A map of the campus is available here; in particular, you can find the location of building D there.
  • All talks take place in the lecture hall D2 (Hörsaal D2) on the ground level of building D. The lecture hall is equipped with 6 excellent blackboards and a video beamer. You can either use all blackboards, or the video beamer and 3 blackboards. If you wish to use the beamer, then make sure that all electronics is set up and the presentation is running properly before the talk begins. If you choose to use the organizer's laptop (which may speed up the process, and is encouraged), please bring the pdf of your talk on a usb-stick (or, even better, send it in advance, no later than Monday, August 11, by email).
  • All coffee breaks take place in the room D2.343 on the second floor of building D (two floors above ground level). As a rule, we offer coffee, tea, cold beverages, biscuits and cake.
  • Conference materials will be available Tuesday and Wednesday in room D2.343 during the coffee breaks. Access codes for WLAN will also be handed out there.
  • Tuesday during the coffee breaks, you can have a look at the restaurant's menu. Please make your choice for the Conference Dinner already then. The conference dinner takes place in the restaurant Ratskeller, Rathausplatz 1, 33098 Paderborn, Phone 05251-201133 in the town center. We shall meet there Tuesday, August 12 at 7:15 p.m.
  • Tuesday-Friday, you can have lunch in the university cafeteria Mensa (second floor of building ME, one floor above ground level). To pay in cash, please use one of the queues on the right-hand side (the queues on the left are for the use of special chip-cards only).
  • Saturday, we can have lunch in the Chinese-Mongolian Restaurant Shangrila, Warburger Str. 138, 33100 Paderborn, Phone 05251-6938698 close to the university.
  • A map of the campus is available here; in particular, you can find the location of building D there.
  • The weather in Paderborn is expected to be pleasant (but including some rain), with temperatures rising up to 22 degrees Centigrade during the day, and a minimum 10 degrees Centigrade at night.

Tra­vel to and from Pa­der­born

Airports close to Paderborn

  • Paderborn/Lippstadt is the airport closest to Paderborn. There are inexpensive busses from there to Paderborn, or you can take a taxi (which may cost 35 EUR or slightly more).

In many cases, you may not get direct flights to Paderborn-Lippstadt (which is a relatively small airport), and flights to this destination may be more expensive than those to larger airports like Düsseldorf (or Frankfurt):

  • Düsseldorf International Airport is a very convenient (and often inexpensive) choice. Railway travel between Paderborn main railway station and the railway station of the airport takes approximately 2 hours. Depending on the choice of train, the costs of a ticket are 35 EUR or slightly more.

  • Frankfurt International Airport may also be an inexpensive choice. Travelling by train from Frankfurt to Paderborn takes approximately 3 hours.

You may also check the international airports of Dortmund or Hannover. Again, railway travel will take around 2 hours.

Some ho­tels in Pa­der­born

Within easy reach of the university:

Hotels in the city centre or close to it (bus to university or 1/2 h walk)

(The organizer cannot guarantee the correctness, timeliness or availablity of these rates)

Fur­ther in­for­ma­ti­on

  • Public transport: From the city or the main railway station, you can reach the university directly using the busses nos. 4 (in direction `Dahl'), 9 (in direction `Kaukenberg') or 68 (in direction `Schöne Aussicht'). Lines 4 and 9 stop at the bus stop `Uni/Südring' (at the bottom of the campus map, marked there with an `H'), while line 68 stops at `Uni/Schöne Aussicht' (close to the arrow pointing towards `Fanny Nathan Strasse' at the lower right hand corner of the campus map). (The hotel `Campus Lounge' is located in the upper left hand corner, close to the crossing of the streets `Mersinweg' and `Pohlweg'). Tickets can be bought on the bus (and also from vending machines at some bus stops). The buses take an estimated 10-20 minutes.
  • Taxis from the railway station to the campus lounge cost about 10-15 EUROs.
  • Travel to and from the aiport: There are some busses from the airport to Paderborn railway station. You can find bus connections using the English web page www.bahn.de/i/view/USA/en/index.shtml. In the fields start/stop, type airport Paderborn/Lippstadt and Paderborn Hbf, respectively, and select the desired date and time. Of course, you can also take a taxi (in case none is waiting at the airport, you may call one of the local taxi companies, e.g. `Taxi Klima,' Phone 05251-61111. Consult the yellow pages for further taxi companies). Busses are inexpensive, while a taxi from the airport say, to the Campus Lounge costs an estimated 35 EUROs (or even more). The bus stop is only a few meters away from the airport building; a location plan of the airport can be found here (the bus stop is marked with a yellow H').
