*Completely monotone intertwining relations*
Abstract:
In this talk, we introduce the concept of completely monotone intertwining
relations as a strengthening of usual intertwining relations between Markov
semi-groups. We proceed by providing some interesting applications of this
new idea which includes the characterization of ergodic constants and
hypercontractivity estimates for non-self-adjoint semigroups. We
illustrate these results by presenting several examples that have emerged
from the recent literature: discrete-to-continuous interacting particle
models, degenerate hypoelliptic Ornstein-Uhlenbeck processes, and
diffusion-to-jump Jacobi processes. This talk is based on a joint a work
with L. Miclo (IMT Toulouse).
Tutti gli interessati sono invitati a partecipare.
