Abstract
We generalize Herman’s method (presented by him at a conference in Lyon in 1990) for constructing invariant n-tori in nearly integrable Hamiltonian systems with N degrees of freedom and degenerate frequency mappings. Whereas M. R. Herman considered the case n = N, we treat the cases n = N and n < N in a unified way. The well-known results by L. H. Eliasson and J. Pöschel on the persistence of elliptic invariant tori in Hamiltonian systems turn out to be particular cases of more general theorems obtained via our approach.
