The object of this week is to bring together specialists in the domains of Riemannian geometry, low-dimensional topology and geometric group theory to take stock of current interactions and encourage new exchanges in this area of rapid progress.

Since the number of places at CIRM is restricted, we strongly encourage all those who plan to take part in the conference to pre-register as soon as possible. Pre-registration will close at the end of October, 2017. Note that we cannot ensure participation without pre-registration or beyond the number of available places.​

The organisers will be able to cover living expenses for a limited number of students and young researchers. Students and young researchers wishing to have their living expenses covered must apply for funding when pre-registering.

Les pré-inscriptions se clôtureront fin octobre 2017. Les inscriptions seront limitées par les places disponibles, et les demandes des personnes pré-inscrites seront considérées en priorité.

Les organisateurs disposent d’un budget pour couvrir les frais de séjour d’un nombre limité d’étudiants et jeunes chercheurs. Afin de bénéficier de cette aide, merci d’en faire la demande lors de la pré-inscription.

L’objet de cette semaine sera de réunir des spécialistes de géométrie riemannienne, topologie de basse dimension et géométrie des groupes afin de faire le point sur leurs interactions et de stimuler de nouvelles passerelles entre ces thèmes très porteurs.
