Lower Bound for the Coarse Ricci Curvature of Continuous-Time Pure-Jump Processes
We obtain a lower bound for the coarse Ricci curvature of continuous-time pure-jump Markov processes, with an emphasis on interacting …

Convergence of a non-failable mean-field particle system
The existing literature contains many examples of mean-field particle systems converging to the distribution of a Markov process …

Uniform tightness for time-inhomogeneous particle systems and for conditional distributions of time-inhomogeneous diffusion processes
In this article, we consider time-inhomogeneous diffusive particle systems, whose particles jump from the boundary of a bounded open …

Quasi-stationary distributions and particular methods for the approximation of conditioned processes
My PhD thesis focuses on the study of the distributions of stochastic processes with absorption and their approximation. This processes …

Interacting Particle Systems and Yaglom Limit Approximation of Diffusions with Unbounded Drift
We study the existence and the exponential ergodicity of a general interacting particle system, whose components are driven by …

Approximation of quasi-stationary distributions for 1-dimensional killed diffusions with unbounded drifts
The long time behavior of an absorbed Markov process is well described by the limiting distribution of the process conditioned to not …
