Vanishing discount and viscosity selection problems for mechanical Hamilton--Jacobi equations
Abstract
We study simultaneous vanishing discount and viscosity limits for mechanical Hamilton--Jacobi equations on the n-dimensional torus. In the critical regime, we explicitly identify the selected limit in terms of the critical Mañé potential and the quadratic behavior of the potential near its wells. We also obtain quantitative and sharp convergence estimates in the subcritical regime. In the supercritical regime, we prove convergence when the local harmonic ground-state energy of the potential has a unique minimizer among the wells. Finally, we establish a concentration phenomenon of the associated Gibbs measures.
