Abstract:
The orbital stability of pendulum-like oscillations of a heavy rigid body with a fixed point in
the Bobylev – Steklov case is investigated. In particular, a nonlinear study of the orbital stability
is performed for the so-called case of degeneracy, where it is necessary to take into account terms
of order six in the Hamiltonian expansion in a neighborhood of the unperturbed periodic orbit.
Keywords:
rigid body, rotations, oscillations, orbital stability, Hamiltonian system, local
coordinates, normal form.
