Martin boundary of a space-time Brownian motion with drift killed at the boundary of a moving cone
Sandro Franceschi
We study a space-time Brownian motion with drift B(t)=(t_0+t,y_0+W(t)+t) killed at the moving boundary of the cone {(t,x):0<x<t}. This article determines the parabolic Martin bound…
Reflected Brownian Motion in a wedge: sum-of-exponential absorption probability at the vertex and differential properties
Jules Flin, Sandro Franceschi
We study a Brownian motion with drift in a wedge of angle which is obliquely reflected on each edge along angles and . We assume that the classical parameter $…
Generators of measure-valued jump diffusions and convergence rate of diffusive mean-field models
Xavier Erny
The paper has two objectives: proving that the rate of convergence in distribution for mean-field models in CLT regime is , and obtaining explicit expressions for the inf…
Escape and absorption probabilities for obliquely reflected Brownian motion in a quadrant
Philip Ernst, Sandro Franceschi, Dongzhou Huang
We consider an obliquely reflected Brownian motion with positive drift in a quadrant stopped at time , where is the first hitting time of th…
Sequential Monte Carlo smoothing for general state space hidden Markov models
Randal Douc, Aurélien Garivier, Eric Moulines +1
Computing smoothing distributions, the distributions of one or more states conditional on past, present, and future observations is a recurring problem when operating on general hi…
