On joint returns to zero of Bessel processes
Quentin Berger, Loïc Béthencourt, Camille Tardif
In this article, we consider joint returns to zero of Bessel processes (): our main goal is to estimate the probability that they avoid having joint returns to zero fo…
Persistence problems for additive functionals of one-dimensional Markov processes
Quentin Berger, Loïc Béthencourt, Camille Tardif
In this article, we consider additive functionals of a càdlàg Markov process on . Under some general conditions on…
On The Simulated Annealing In
Nicolas Fournier, Camille Tardif
Using a localization procedure and the result of Holley-Kusuoka-Stroock [7] in the torus, we widely weaken the usual growth assumptions concerning the success of the continuous-tim…
Simulated Annealing In With Slowly Growing Potentials
Nicolas Fournier, Pierre Monmarché, Camille Tardif
We use a localization procedure to weaken the growth assumptions of Royer [8], Miclo [4] and Zitt [9] concerning the continuous-time simulated annealing in . We show…
On the Poisson boundary of the relativistic Brownian motion
Jürgen Angst, Camille Tardif
In this paper, we determine the Poisson boundary of the relativistic Brownian motion in two classes of Lorentzian manifolds, namely model manifolds of constant scalar curvature and…
Anomalous diffusion for multi-dimensional critical Kinetic Fokker-Planck equations
Nicolas Fournier, Camille Tardif
We consider a particle moving in dimensions, its velocity being a reversible diffusion process, with identity diffusion coefficient, of which the invariant measure behave…
One dimensional critical Kinetic Fokker-Planck equations, Bessel and stable processes
Nicolas Fournier, Camille Tardif
We consider a particle moving in one dimension, its velocity being a reversible diffusion process, with constant diffusion coefficient, of which the invariant measure behaves like…
Hypocoercive estimates on foliations and velocity spherical Brownian motion
Fabrice Baudoin, Camille Tardif
By further developing the generalized -calculus for hypoelliptic operators, we prove hypocoercive estimates for a large class of Kolmogorov type operators which are defined on n…
Kinetic Brownian motion on Riemannian manifolds
Jürgen Angst, Ismaël Bailleul, Camille Tardif
We consider in this work a one parameter family of hypoelliptic diffusion processes on the unit tangent bundle of a Riemannian manifold , collectiv…
Dévissage of a Poisson boundary under equivariance and regularity conditions
Jürgen Angst, Camille Tardif
We present a method that allows, under suitable equivariance and regularity conditions, to determine the Poisson boundary of a diffusion starting from the Poisson boundary of a sub…
Lyapunov spectrum of a relativistic stochastic flow in the Poincaré group
Camille Tardif
We determine the Lyapunov spectrum and stable manifolds of some stochastic flows on the Poincaré group associated to Dudley's relativistic processes.
A Poincaré cone condition in the Poincaré group
Camille Tardif
Gradinaru and Ben Arous described the behavior of the Green function of a sub-elliptic diffusion. We adapt their proof in the general setting of an hypoelliptic diffusion and deduc…
