Jérémy Blanc - Universität Basel - Mathematisches Institut
Workshop ALGEBRA and GEOMETRY
Workshop for PhD students, supported by the Swiss doctoral program of mathematics
Bern, September 10-11, 2012
The aim of this workshop was to give opportunity to PhD students of the program (Basel, Bern, Fribourg, Geneva, Lausanne, Neuchâtel) to give a talk on their subject to other students and also to some researchers of the topic. It was also a chance to have discussions between the students after the talks or during the social dinner.

The talks were supposed to be not too technical in order to be understandable by all other students of the fields.
