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…
An application of Sparre Andersen's fluctuation theorem for exchangeable and sign-invariant random variables
Quentin Berger, Loïc Béthencourt
We revisit here a famous result by Sparre Andersen on persistence probabilities for symmetric random walks . We give…
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 critical curves of the Pinning and Copolymer models in Correlated Gaussian environment
Quentin Berger, Julien Poisat
We investigate the disordered copolymer and pinning models, in the case of a correlated Gaussian environment with summable correlations, and when the return distribution of the und…
