Nonlinear partial and ordinary differential equations appear in mathematical models for many problems in science and engineering. Many interesting phenomena are due to the nonlinearity of the equations. The desire to describe and predict such phenomena by mathematical analysis of the equations and their solutions continues to have a profound impact on the research objectives in both pure and applied mathematics. This has strongly influenced the development of the modern theory of nonlinear partial differential equations, as well as that of finite and infinite dimensional dynamical systems, nonlinear functional analysis and numerical analysis. This conference brings together a group of experts from different fields in mathematics, stimulating interaction and new collaborations in an exciting field.

17.30- Weekend

Getting to Amsterdam and your hotel

Detailed information on how to reach the VU by public transportation, car or from our national airport can be found here.

The cheapest way to get from the airport to the hotels (Aalders and ACRO, see below) is to take a train from Schiphol airport to Amsterdam Zuid/WTC. These trains leave quite frequently from Platform 1 and 2. Note that these are NOT the trains to Amsterdam Central Station. Beware of pickpockets.

At WTC you take tram 5 (you have to go down the stairs turn left and take the next stairs going up on your right to the other platform), direction Central Station. Exit at the Hobbemastraat tram stop. Walk back in the direction from which you came by tram and take the first right. You are now in the Jan Luyckenstraat. Hotel Aalders is situated at number 13-15i and Hotel ACRO at number 44.

If you want to go from WTC directly to the University take tram 5 or express tram 51 in the opposite direction, see below

For the train you need a ticket that you can buy at the counter or from the machine. Also buy a "strippenkaart" for the tram.

Most of the guests will be accomodated in hotel Aalders. The full address of the hotel is given below as well as a small map of the surrounding streets. Below you can find a description of how to get from the hotel to the VU and back.

Aalders Hotel BV
J Luykenstr 13-15
1071CJ Amsterdam
Tel: 020 673 4027
Hotel Aalders

Some guests will stay in Hotel Acro, which is located in the same street (Jan Luijkenstraat 44 1071CR Amsterdam, tel. 020 662 0526).

Getting to the VU and back

Hotel Aalders to VU tram stop

Leave the hotel and turn right. Take the first left and you almost immediately arrive at the Hobbemastraat tram stop. Take tram 5 in the direction of Amstelveen (20-25 minutes), exit at the VU tram stop. You can also take a cab to the following address:
Vrije Universiteit
De Boelelaan 1105
Amsterdam

VU tram stop to Hotel Aalders

Take tram 5 in the direction of Central Station (20-25 minutes), alight: at the Hobbemastraat tram stop. Walk back in the direction from which you came by tram and take the first right. You are now in the Jan Luyckenstraat. Hotel Aalders is situated at number 13-15.

Getting to the right room in the VU

VU Campus

VU tram stop to the Aula (De Boelelaan 1105)

Enter the VU Main Building (Hoofdgebouw) through the front entrance and go to the right. Now take the big stairs to the second floor. Turn left and go up one more flight of stairs. The door to the aula is now straight ahead.

VU tram stop to lecture room Q 1.05 (De Boelelaan 1081)

Instead of walking to the front entrance of the VU Main Building (Hoofdgebouw), walk to the rear of the platform. Here you can cross the street and take a little pathway between the VU Main Building and the Science Building. Walk straight on around the pond and take the first entrance on your left side: De Boelelaan 1081. Now go to the first floor and go west. After 50 meters the lecture room is to your right. In the picture it is the extension of the building between 1081 and 1083.
