Perturbations of degenerate coisotropic invariant tori of Hamiltonian systems

  • I. O. Parasyuk

Abstract

We consider a Hamiltonian system with a one-parameter family of degenerate coisotropic invariant tori. We prove a theorem on the preservation of the majority of tori under small perturbations of the Hamiltonian.
