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.…
Gibbs principle with infinitely many constraints: optimality conditions and stability
Louis-Pierre Chaintron, Giovanni Conforti, Julien Reygner
We extend the Gibbs conditioning principle to an abstract setting combining infinitely many linear equality constraints and non-linear inequality constraints, which need not be con…
Existence and global Lipschitz estimates for unbounded classical solutions of a Hamilton-Jacobi equation
Louis-Pierre Chaintron
The purpose of this article is to prove existence, uniqueness and uniform gradient estimates for unbounded classical solutions of a Hamilton-Jacobi-Bellman equation. Such an equati…
