Henryk ŻołądekBirkhoff normalization, Bifurcations of Hamiltonian systems and the Deprits formulaWe consider Hamiltonian autonomous systems with n degrees of freedom near a singular point. In the case of absence of resonances of order <5 we present a direct computation of the Birkhoff normal form. In the case of two degrees of freedom we study one-parameter deformations of the 0 : 1; 1 : 1 and 2 : 1 resonant singularities. The obtained results are used in a direct derivation of the Deprits formula for the isoenergetic degeneracy determinant in the restricted three body problem. Finally, we present a new case of Lyapunov stable libration point in the restricted four body problem. |
