Focusing Gibbs measures with harmonic potential

Tristan Robert, Kihoon Seong, Leonardo Tolomeo +1

In this paper, we study the Gibbs measures associated to the focusing nonlinear Schrödinger equation with harmonic potential on Euclidean spaces. We establish a dichotomy for norma…

Independence preserving property of Kummer laws

Efoevi Angelo Koudou, Jacek Wesołowski

We prove that if are positive, independent, non-Dirac random variables and if for , , $$ ψ_{α,β}(x,y)=\left(y\,\tfrac{1+β(x+y)}{1+αx+βy},\;x\,\tfrac{1+α(x+…

Quasi-limiting estimates for periodic absorbed Markov chains

Nicolas Champagnat, Denis Villemonais

We consider periodic Markov chains with absorption. Applying to iterates of this periodic Markov chain criteria for the exponential convergence of conditional distributions of aper…

Binary branching processes with Moran type interactions

Alexander M. G. Cox, Emma Horton, Denis Villemonais

The aim of this paper is to study the large population limit of a binary branching particle system with Moran type interactions: we introduce a new model where particles evolve, re…

The Multi-type Bisexual Galton-Watson Branching Process

Coralie Fritsch, Denis Villemonais, Nicolás Zalduendo

In this work we study the bisexual Galton-Watson process with a finite number of types, where females and males mate according to a ''mating function'' and form couples of differen…

General diffusion processes as the limit of time-space Markov chains

Alexis Anagnostakis, Antoine Lejay, Denis Villemonais

We prove the convergence of the law of grid-valued random walks, which can be seen as time-space Markov chains, to the law of a general diffusion process. This includes processes w…

Hyperbolic Anderson model 2: Strichartz estimates and Stratonovich setting

Xia Chen, Aurélien Deya, Jian Song +1

We study a wave equation in dimension with a multiplicative space-time Gaussian noise. The existence and uniqueness of the Stratonovich solution is obtained under so…

Quasi-stationary behavior for an hybrid model of chemostat: the Crump-Young model

Bertrand Cloez, Coralie Fritsch

The Crump-Young model consists of two fully coupled stochastic processes modeling the substrate and microorganisms dynamics in a chemostat. Substrate evolves following an ordinary…

Approximations of dispersive PDEs in the presence of low-regularity randomness

Yvonne Alama Bronsard, Yvain Bruned, Katharina Schratz

We introduce a new class of numerical schemes which allow for low regularity approximations to the expectation , where denotes the -th Four…

A central limit theorem for continuous-time Markov processes conditioned not to be absorbed

William Oçafrain

This paper aims to establish a central limit theorem for Markov processes conditioned not to be absorbed under a very general assumption on quasi-stationarity for the underlying pr…

Perfect sampling of stochastic matching models with reneging

Thomas Masanet, Pascal Moyal

In this paper, we introduce a slight variation of the Dominated Coupling From the Past algorithm (DCFTP) of Kendall, for bounded Markov chains. It is based on the control of a (typ…

Functional convergence to the local time of a sticky diffusion

Alexis Anagnostakis

We establish the consistency of a local time approximation of a diffusion at a sticky threshold based on high-frequency observations. First, we prove the result for sticky Brownian…

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…

Quasi-stationary distributions in reducible state spaces

Nicolas Champagnat, Denis Villemonais

We study quasi-stationary distributions and quasi-limiting behavior of Markov chains in general reducible state spaces with absorption. We propose a set of assumptions dealing with…
