Stable semigroups on homogeneous trees and hyperbolic spaces
We prove the kernel estimates related to subordinated semigroups on homogeneous trees. We study the long time propagation problem. We exploit this to show exit time... -

On the quantitative quasi-isometry problem: transport of Poincaré inequalitie...
We consider a quantitative form of the quasi-isometry problem. We discuss several arguments which lead us to different results and bounds of quasi-isometric...
