Аннотация:
This paper considers a class of nearly integrable reversible systems whose unperturbed
part has a degenerate frequency mapping and a degenerate equilibrium point. Based on
some KAM techniques and the topological degree theory, we prove the persistence of multiscale
degenerate hyperbolic lower-dimensional invariant tori with prescribed frequencies.
