Non-linear stability of the Hamiltonian system on linear approximation
We consider the conditions of preserving stability of stationary point of linear Hamiltonian system with small non-linear perturbations. The algorithm
for selection those areas of the set of stability for which the mentioned above conditions are satisfied. The application of the algorithm is demonstrated on a 5-parametric problem with 4 degrees of freedom.
