Generalized Langevin And Nos{é}-hoover Processes Absorbed At The Boundary Of A Metastable Domain
Arnaud Guillin, D I Lu, Boris Nectoux +1
In this paper, we prove in a very weak regularity setting existence and uniqueness of quasi-stationary distributions as well as exponential conver- gence towards the quasi-stationa…
