  • Hamiltonian dynamics, localized solution, orbit-flip, homoclinic bifurcation, hyperbolic set, superhomoclinic orbit




We prove that the orbit-flip bifurcation in the systems with a smooth first integral (e.g. in the Hamiltonian ones) leads to appearance of infinitely many multi-pulse self-localized solutions. We give a complete description to this set in the language of symbolic dynamics and reveal the role played by special non-selflocalized solutions (e.g. periodic and heteroclinic ones) in the structure of the set of self-localized solutions. We pay a special attention to the superhomoclinic ("homoclinic to homoclinic") orbits whose presence leads to a particularly rich structure of this set.
