Sharp O(ε log(1/ε)) global and O(ε) almost-everywhere convergence rates are established for periodic homogenization of viscous quadratic Hamilton-Jacobi equations.
Proves 1/2-rate quantitative ergodicity for Hamilton-Jacobi equations in dynamic random media via new almost-Lipschitz regularity for the metric problem.
PDE criteria based on the critical value of the Hamiltonian and viscosity subsolutions determine Lyapunov stability and instability for stationary solutions of contact-type Hamilton-Jacobi equations with continuous convex coercive Hamiltonians.
Under monotonicity, solutions to static contact Hamilton-Jacobi equations with periodicity ε converge uniformly at rate O(ε) to the solution of an effective homogenized equation identified via Mather measures.
