Vanishing viscosity limits for space-time periodic   Hamiltonian-Jacobi-Bellman equations
  Extending previuos results, we study the vanishing viscosity limit of solutions of space-time periodic Hamiltonian-Jacobi-Belllman equations, assuming that the "Aubry set" is the union of a finite number of hyperbolic periodic orbits of the Hamiltonian flow.
