S. Albeverio et A. Daletskii, ASYMPTOTIC QUANTIZATION FOR SOLUTION MANIFOLDS OF SOME INFINITE-DIMENSIONAL HAMILTONIAN-SYSTEMS, Journal of geometry and physics, 19(1), 1996, pp. 31-46
The solution manifolds of some classes of Hamiltonian systems in Hilbe
rt phase spaces are considered. Pseudodifferential operators with symb
ols on these manifolds are defined.
