Abstract:
A generalized model of Hamiltonian mechanics is considered. It includes two special cases: a model of the dynamics of three magnetic vortices in ferromagnets and a model of the dynamics of three hydrodynamic vortices in a perfect fluid. A constraint is imposed on the system by fixing one of the vortices at the point of origin. The system of the constrained problem of three magnetic vortices is a completely Liouville-integrable Hamiltonian system with two degrees of freedom. For this system, we find an augmented bifurcation diagram, perform a reduction to a system with one degree of freedom, and investigate level curves of the reduced Hamiltonian in detail. The obtained results show the presence of noncompact bifurcations and a noncritical bifurcation line.
