Programme
All activities will take place at the Facultad de Ciencias of the Universidad de Cantabria, located at Avenida de Los Castros 48 (see this Google maps link).
The program will consist of four plenary talks, 42 contributed talks (20 minutes) in two parallel sessions, and a poster session. The four plenary speakers are:
Marthe Bonamy, Université de Bordeaux.
János Pach, EPFL Lausanne and Rényi Institute Budapest.
Guillem Perarnau, Universitat Politècnica de Catalunya.
Pascal Schweitzer, Technische Universität Darmstadt.
The full programme and the list of accepted contributions can be downloaded as pdf files.
On Tuesday evening there will be a social dinner for registered participants, free of charge, at Hotel Silken Rio. Please fill this form to let us know whether you plan to come, and your choice of main dish.
