Cutoff in separation profile for the flat torus, sphere, and projective spaces
Koléhè Coulibaly-Pasquier
In this paper we show that the cutoff in separation profile for Brownian motion on flat torus T n\,; on spheres S n\,; on real, complex and quaternionic projective space resp. P n…

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…

On the separation cut-off phenomenon for Brownian motions on high dimensional rotationally symmetric compact manifolds
Koléhè Coulibaly-Pasquier, Marc Arnaudon, Laurent Miclo
Given a family of rotationally symmetric compact manifolds indexed by the dimension and a weight function, the goal of this paper is to investigate the cut-off phenomenon for the B…
