| Research Abstract |
We introduced the notion of ergodicity at infinite energy level in both quantum and classical mechanics. The notion allows us to give a necessary and sufficient condition in terms of microlocal properties of eigenfunctions of a quantum hamiltonian such that the corresponding classical dynamical system is ergodic. Especially, a new insight into quantum ergodicity due to Snirelman, Zelditch and Colin de Verdiere was given.
