Abstract. The anisotropic Manev problem, which lies at the intersection of
classical, quantum, and relativity physics, describes the motion
of two point masses in an anisotropic space under the influence of a Newtonian
forcelaw with a relativistic correction term. Using an extension of the
Poincar\'eMelnikov method, we first prove that for weak anisotropy, chaos
shows up on the zeroenergy manifold. Then we put into the evidence a class
of isolated periodic orbits and show that the system is nonintegrable.
Finally, using the geodesic deviation approach, we prove the existence of a
large nonchaotic set of uniformly bounded and collisionless solutions.
