On Invariant Tori of Nearly Integrable Hamiltonian Systems with Quasiperiodic Perturbation
<p/> <p>We are concerned with the persistence of frequency of invariant tori for analytic integrable Hamiltonian system with quasiperiodic perturbation. It is proved that if the unperturbed system satisfies the Rüssmann's nondegeneracy condition and has nonzero Brouwer'...
