Du 2 au 3 mars 2015
IRMA
The workshop "Spherical and hyperbolic geometry" will take place at Institut de Recherche Mathématique Avancée (University of Strasbourg and CNRS) on March 2-3, 2015.
Organizers : A. Papadopoulos and D. Slutskiy (Strasbourg)
Each speaker will present a classical result in non-Euclidean (spherical and/or hyperbolic) geometry together with modern ramifications.
The invited speakers include :
- N. A'Campo (Basel)
- V. Alberge (Strasbourg)
- N. Bergeron (Jussieu)
- C. Boubel (Strasbourg)
- S. Dumitrescu (Nice)
- B. Ettaoui (Mulhouse)
- F. Fillastre (Cergy)
- E. Frenkel (Strasbourg)
- S. L. Ho (Luxembourg)
- A. Papadopoulos (Strasbourg)
- D. Slutskiy (Strasbourg)
- S. Yamada (Tokyo)
The talks will be in English and they are intended for a general audience. Graduate students and young mathematicians are welcome.
Registration is required (and free of charge) at this link. Hotel booking can be asked for through the registration link.
