We apply the averaging theory to a class of three-dimensional autonomous quadratic polynomial differential systems known as Lorenz-type systems, and we prove the existence of a small amplitude periodic orbit bifurcating from a degenerate zero-Hopf equilibrium of these systems.

In this work, applying general results from averaging theory, we find periodic orbits for a class of Hamiltonian systems H whose potential models the motion of elliptic galaxies. Using the above periodic orbits on the energy level H = h we provide information about the non-integrability, in the sense of Liouville-Arnold, of the respective Hamiltonian system generated by H.
