Social Events

1) There will be an informal wine and cheese party in the evening on the arrival day Monday, June 4, starting at 6 p.m. and ending about midnight.

2) The afternoon of Thursday, June 7, will be free from lectures. Instead, there will be a sea excursion from Göteborg to the island of Marstrand. The ship used will be Sweden's largest sailing ship, t/s Gunilla. A lavish dinner on seafood, roast beef and salads will be served on board. It is a spectacular tour through the archipelago of Göteborg. Marstrand is a small island with a little town and an old fortress. The houses are built in a traditional Swedish style. The sea tour from Göteborg takes about four hours, the journey back will be by bus.

The excursion is heavily sponsored by the organizers, but it is still not for free. The cost per participant is 250 SEK, to be paid at the registration desk on arrival. Please note that the ship only takes a limited number of passengers. It is therefore essential that you reserve a place as soon as possible. To do so, please send an e-mail to the Organizing Committee with the subject line "Sea Excursion". Let us know if you have any special food requirements. NB: you need to be registered as a participant in the conference.

If you want to read what the Dutch Mathematician ter Maten wrote about a sea tour to Marstrand on a similar occasion in 1998, click here!

3) In the evening of Friday, June 8, there will be a free reception at the City Hall for all participants of the conference.


The Conference will take place at the Mathematics Centre (Matematiskt centrum):
Visiting address: Eklandagatan 86
Postal address: The School of Mathematical and Computing Sciences,
Chalmers University of Technology,
SE-412 96 Goteborg, Sweden


How to get to the Conference:

Arriving Landvetter Airport
On the arrival day June 4 from 12 noon to 8 pm there will be a desk at Landvetter airport (International arrivals) where you can contact representatives of the conference organisers. Look out for them after passing Customs.
Between 12 noon and 8 pm there will be a bus shuttle taking arriving participants to their hotels. The bus will only take eight passengers at the time so you may have to wait at the airport. In case you would rather use public transportation you can take the Airbus to Kungsportsplatsen, where you can change to buses 40 or 41 to Pilbågsgatan (end station). The fare is 50 SEK for the Airbus and 16 SEK for buses and trams within Goteborg. A taxi from the airport to the hotels or the Mathematics Centre costs at most 300 SEK (ask for fixed price). On June 4 the reception at SGS has office hours 9 am to 7 pm. In case you arrive later on June 4 and wish us to pick up your key from SGS and have it ready for you at the Mathematics Centre, please let us know. If you arrive on any day other than June 4 and are staying at SGS, please contact the SGS hotel for instructions.

Arriving Central Railway Station

Take bus 60 to the Mathematics Centre. The fare is 16 SEK.

In case of problems on the arrival day June 4, you may call us on 0733-148877 (+46-733 148877 from abroad). NB: This phone number is only available on June 4!

How to register: The Registration desk at the Mathematics Centre will be open on June 4 from 3 pm to 9 pm and on June 5 from 8 am to 9 am. In case you arrive later, please contact the organisers. Those of you who have registered for the Sea Excursion have to pay 250 SEK on registration (400 SEK for accompanying persons). Please note that if you fail to do so by June 5, your place will be taken by somebody on the waiting list.

Maps: You will receive a city map and a campus map on registration.

Money exchange: FOREX usually has the most profitable exchange rate. You can find them at Landvetter airport (International), office hours 5.15 am to 11 pm, at the railway station and in Kungsportsavenyn.

Local transportation: The Mathematics Centre is located at the south end of the Chalmers University of Technology campus, just two kilometers (1.25 miles) from the very heart of the city, and the main attractions of Goteborg are just a fifteen minute walk away. If you travel by public transport, you can reach the Mathematics Centre by bus (lines 60, 40, 41 and 51, stop at Pilbågsgatan, close to the building) or by tram (lines 6, 7 and 8, stop at Chalmers just north of the campus).

How to telephone in Sweden: There are very few public phones that operate with coins. It is more convenient and also cheaper to use telephone cards. You can find them at most places selling newspapers.

Breakfast: Breakfast is included at Panorama and Ljungbacken. At SGS you will have access to a kitchen with basic equipment. There is a food store nearby (ICA Kroken) which is open between 9 am and 10 pm on weekdays and between 11 am and 10 pm on weekends.

Lunch and dinner: There is a number of lunch restaurants close to the Mathematics Centre. Prices for lunch vary between 40 SEK and 60 SEK. For dinner we recommend that you choose a restaurant in Kungsportsavenyn or in Linnegatan. For more information contact the "locals".

Computer facilities: All participants will get personal accounts. Computers in the labs close to the Lecture Hall have been reserved for the participants. More information will be found in the folder handed out on registration.

Opening hours:
Banks are open weekdays 9.30 am -- 3 pm.
Post offices are open weekdays 10 am -- 6 pm, Saturday 10 am -- 1 pm.

Swedish holidays: June 2 to June 4 are holidays in Sweden and shops are in general closed. However, many food stores are open, though with reduced
opening hours.

Weather: Bring your bathing suit and a warm sweater!!!

Welcome to Göteborg!
