Shape Analysis Workshop in Grundsund
July 27 - August 1, 2015

This is the third edition of the previously held
  • Math on the Beach - Shape Analysis Workshop in Foxton Beach, New Zealand, 2013
  • Math in the Cabin - Shape Analysis Workshop in Bad Gastein, Austria, 2014 (proceedings)
This year the workshop is in Grundsund, in the archipelago of western Sweden. The theme is
  • Infinite-dimensional Riemannian geometry
  • Shape analysis
  • Image matching
  • Computational anatomy
  • Topological hydrodynamics

UPDATE: The organizers would like to thank all the participants for a very interesting and productive week. The proceedings are now available here, with the following designation:

K. Modin and S. Sommer (Eds.), Proceedings Of Math On The Rocks Shape Analysis Workshop In Grundsund, Zendo, 2015. DOI:10.5281/zendo.33558

Getting there


The easiest way to get to Grundsund is to fly to Gothenburg, then take the airport bus to the city, then take bus 841 from Gothenburg C towards Lysekil. By bus, it is about 2 hours to get from Gothenburg C to Grundsund. By car, about 1.5 hours.

Workshop venue


The seminars and discussions will be held in the club house of the boat-club, located right on the jetty. The club house has a white-board and there will also be a beamer. In addition, there is a fairly large, well-equipped kitchen. Following the tradition of the previous meetings, we will take it in turns to arrange lunches and meals. There is a supermarket about a 10 min walk away from the boat-club, opening hours 9.00-21.00.


As usual, lodging will be in shared rooms. The rooms are located in different houses in the harbour of Grundsund (see picture above), about 1-5 min from the boat-club. Bring bed-sheets and a towel. For those of you who are bringing family (and therefore would like private lodging), there is a hostel 5-10 min walk from the jetty. If you want to book there, do it quickly, as it is usually very busy during summer. Contact information to the hostel:, +46 523 20406 (land-line) or +46 702-56 80 28 (cell phone). Mention that you're attending the "Chalmers conference" when you talk with them.



The island of Skaftö, on which Grundsund is the main village, has great surroundings. Grundsund in itself is very cozy. There are many walks with stunning views over the rock archipelago. Make sure to bring bathers, as you will not be able to resist leaping out from the rocks into the sea. There is a lot of marine life, so it is worthwhile to bring snorkling gear. One of the afternoons (probably Wednesday) we will do sea kayaking. This will allow us to explore the outer archipelago, and maybe spot seals. Our experienced guide will be Christina Ingemarsdotter who is running the kayaking rental company in Grundsund. There will also be opportunities to do  kayaking in the evenings, after seminars and discussions. More information about the kayaking later.
