Large time behaviour for the semigroup of the kinetic Brownian motion in the plane
Magalie Bénéfice, Michel Bonnefont, Marc Arnaudon +1
We establish an integration by parts formula for the semigroup in time of the kinetic Brownian motion in the Euclidean plane together with its velocity in the circle. The sto…

Cutoff in separation for compact harmonic manifold
Koléhè Coulibaly-Pasquier, Magalie Bénéfice
We show that cutoff in separation occurs for Brownian motion in some families of compact harmonic manifolds. We compute the cutoff time and windows in four families of compact harm…
