Abstract

Studying the two-body problem associated to an anisotropic Schwarzschild-type field, Mioc et al. (2003) did not succeed in proving the existence or non-existence of periodic orbits. Here we answer this question in the affirmative. To do this, we start from two basic facts: (1) the potential generates a strong force in Gordon’s sense; (2) the vector field of the problem exhibits the symmetries S i , \(i =\overline {1, 7} \), which form, along with the identity, an Abelian group of order 8 with three generators of order 2. Resorting to S2 and S3, in connection with variational methods (particularly the classical lower-semicontinuity method), we prove the existence of infinitely many S2- or S3-symmetric periodic solutions. The symmetries S2 and S3 constitute an indicator of the robustness of the classical isotropic Schwarzschild-type system to perturbations (as the anisotropy may be considered).
