Abstract: |
We consider autonomous Newtonian systems with Coriolis forces in two and three dimensions and study the existence of branches of periodic orbits emanating from equilibria. While Lyapunov’s center theorem applies locally in the nondegenerate, nonresonant context, equivariant degree theory provides a global answer which is significant also in some degenerate cases.
We apply our abstract results to a problem from Celestial Mechanics.
More precisely, in the three-dimensional version of the Restricted Triangular Four-Body Problem with possibly different primaries our results show the existence of at least seven branches of periodic orbits emanating from the stationary points.
This is a joint work with Anna Golebiewska, Ernesto Perez-Chavela and Slawomir Rybicki
