In 1995, Besson, Courtois and Gallot [BCG] repeated the proof of a theorem that stated that any positive measure µ on the boundary M(∞) of a locally symmetric space M with rank 1 admits a unique center of mass as the solution of the equation: where Bθ is the Busemann function for θ ∈ M(∞). In the higher rank case it is obvious that the center of mass does not exist anymore. As an example...

Slope instabilities such as mudflows, debris flows or landslides have lately raised much concern in Switzerland, since various major events have occurred during the last decade, resulting in major landscape disturbances, as well as costly damage to infrastructure. This demonstrated the necessity to better understand the causes and dynamics of such processes. This research work aims at defining...
