Abstract. It has been proved by S.L.Ziglin (1982), for a large class
of 2-degree-of-freedom (d.o.f) Hamiltonian systems,
that transverse intersections of the invariant
manifolds of saddle fixed points imply infinite branching of
solutions in the complex time plane and the non--existence of a second
analytic integral of the motion. Here, we review in detail our recent results,
following a similar approach to show the existence
of infinitely--sheeted solutions for 2 d.o.f.
Hamiltonians which exhibit, upon perturbation, subharmonic bifurcations
of resonant tori around an elliptic fixed point (Bountis and Rothos, 1996).
Moreover, as shown recently, these Hamiltonian systems are non--integrable
if their resonant tori form a dense set.
These results can be extended to the case where
the periodic perturbation is not Hamiltonian.
