Poincaré inequalities and hitting times
Patrick Cattiaux, Arnaud Guillin, Pierre-André Zitt
Equivalence of the spectral gap, exponential integrability of hitting times and Lyapunov conditions are well known. We give here the correspondance (with quantitative results) for…

Resonances for a diffusion with small noise
Markus Klein, Pierre-André Zitt
We study resonances for the generator of a diffusion with small noise in :, when the potential F grows slowly at infinity (typically as a sq…
