    Author(s): Smirnov G. E.

    In this paper the local singularities of integrable Hamiltonian systems with two degrees of freedom are studied. The topological obstruction to the existence of a focus-focus singularity with given complexity is found. It is shown that only simple focus-focus singularities can appear in a typical mechanical system. Model examples of mechanical systems with complicated focusfocus singularity are given.
    Keywords: integrable hamiltonian systems, focus-focus singularities, obstruction to the existence of singularities
