Program

The program will consist of two advanced courses (3h lectures and 2h problem sessions each), some long (1h) invited talks, plus contributions from participants in the form of short presentations and poster sessions.

On Tuesday evening there is also going to be a public lecture by Rekha Thomas on The algebra and geometry of the pinhole camera.

Schedule: You can download this pdf with the full program, including abstracts.

Rooms: The workshop takes place at the Facultad de Ciencias. On Monday and Tuesday we will primarily use the Aula Magna and Wednesday to Friday the Aula 1. Exceptions to this are:

• Registration will take place in Aula 6.
• Luis Ferroni’s talk on Monday afternoon will take place in Aula 2.
• The Exercise sessions will take place in Aula 5.
• The poster session will take place in the lobby outside Aula Magna.

Monday’s Welcome reception (offered by the City of Santander) will take place at the Palacio de la Magdalena.
Wednesday’s Social Dinner will take place at Bodegas Mazón. (Please fill in this form with your choice, by Thursday January 11th at noon).
