An Elementary Approach To Uniform In Time Propagation Of Chaos

Understand

Based on a coupling approach, we prove uniform in time propagation of chaos for weakly interacting mean-field particle systems with possibly non-convex confinement and interaction potentials.

• The approach is based on a combination of reflection and synchronous couplings applied to the individual particles.
• It provides explicit quantitative bounds that significantly extend previous results for the convex case.
