Workshop on quantitative spectral theory and mathematical physics


The format of the workshop is informal and it is planned that all participants

will give 45 minute talks with ample time reserved for discussions.


Accommodation and organization is provided by hotel Colentum. The price for the conference package is 1932 kn. This includes half board.

Island of Murter is located near the national park Kornati, and the national park Krka is also in vicinity (50 km by car).

The easiest means of transportation is to fly into Zagreb airport and then take a direct bus to Murter (approx 5 hours bus ride).

An alternative is to fly into Zadar or Split airports and take a bus

to Šibenik and a local bus to Murter.

If there is a group of people arriving to Zadar airport

it could be possible to organize a shuttle minibus to the hotel at a more favorable price. The cost of a minibus - max. 8 participants -  is 80 € per minibus. In case there are interested participants please contact

Island of Murter, Croatia, 14-18 September 2011

A particular objective of the workshop is to intensify the cooperation between Croatian and German scientists working in mathematical physics and continue the series of joint Zagreb-Chemnitz seminars, which started in September 2010.
