Summary: We consider a simple model problem which provides us with an example showing that not only periodic trajectories of the classical Hamiltonian system are significant for solutions of asymptotic problems, but the trajectories filling invariant tori also should be taken into consideration. For this model problem, we find the invariant tori and prove that the corresponding Maslov canonical operator gives an asymptotic solution of the problem.
