Freidlin-Wentzell type exit-time estimates for time-inhomogeneous diffusions and their applications
Ashot Aleksian, Stéphane Villeneuve
This paper investigates the exit-time problem for time-inhomogeneous diffusion processes. The focus is on the small-noise behavior of the exit time from a bounded positively invari…
Measure-dependent non-linear diffusions with superlinear drifts: asymptotic behaviour of the first exit-times
Ashot Aleksian, Julian Tugaut
In this paper, we study McKean-Vlasov SDE living in in the reversible case without assuming any type of convexity assumptions for confinement or interaction potentia…
Exit-problem for a class of non-Markov processes with path dependency
Ashot Aleksian, Aline Kurtzmann, Julian Tugaut
We study the exit-time of a self-interacting diffusion from an open domain . In particular, we consider the equation $d{X_t} = - \left( \nabla V(X_t) + \fra…
Self-interacting diffusions: long-time behaviour and exit-problem in the convex case
Ashot Aleksian, Pierre del Moral, Aline Kurtzmann +1
We study a class of time-inhomogeneous diffusion: the self-interacting one. We show a convergence result with a rate of convergence that does not depend on the diffusion coefficien…
On the exit-problem for self-interacting diffusions
Ashot Aleksian, Pierre Del Moral, Aline Kurtzmann +1
We study the exit-time from a domain of a self-interacting diffusion, where the Brownian motion is replaced by for a constant . The first part of this work consists in sh…
