Mean-field limits à la Tanaka and large deviations for particle systems with network interactions
Louis-Pierre Chaintron, Antoine Diez
This article proposes a unified framework to study non-exchangeable mean-field particle systems with some general interaction mechanisms. The starting point is a fixed-point formul…
Geodesic convexity and strengthened functional inequalities in submanifolds of Wasserstein space
Louis-Pierre Chaintron, Daniel Lacker
We study the geodesic convexity of various energy and entropy functionals restricted to (non-geodesically convex) submanifolds of Wasserstein spaces with their induced geometry. We…
Propagation of weak log-concavity along generalised heat flows via Hamilton-Jacobi equations
Louis-Pierre Chaintron, Giovanni Conforti, Katharina Eichinger
A well-known consequence of the Pr{é}kopa-Leindler inequality is the preservation of logconcavity by the heat semigroup. Unfortunately, this property does not hold for more general…
Optimal rate of convergence in the vanishing viscosity for uniformly convex Hamilton-Jacobi equations
Louis-Pierre Chaintron, Samuel Daudin
The purpose of this note is to provide an optimal rate of convergence in the vanishing viscosity regime for first-order Hamilton-Jacobi equations with uniformly convex Hamiltonian.…
Optimal rate of convergence in the vanishing viscosity for quadratic Hamilton-Jacobi equations
Louis-Pierre Chaintron, Samuel Daudin
The purpose of this note is to provide an optimal rate of convergence in the vanishing viscosity regime for first-order Hamilton-Jacobi equations with purely quadratic Hamiltonian.…
Constrained non-linear estimation and links with stochastic filtering
Louis-Pierre Chaintron, Laurent Mertz, Philippe Moireau +1
This article studies the problem of estimating the state variable of non-smooth subdifferential dynamics constrained in a bounded convex domain given some real-time observation. On…
