Quasiclassical surface of section perturbation theory
Quasiclassical surface of section perturbation theory
Perturbation theory, the quasiclassical approximation, and the quantum surface of section method are combined. This gives a new solution of the long-standing problem of quantizing the resonances generically appearing in classical perturbation theory. Our method is restricted to two dimensions. In that case, however, the results are simpler, more explicit, …
