Demystifying autoparallels in alternative gravity
Yuri N. Obukhov, Dirk Puetzfeld
Abstract
Autoparallel curves along with geodesic curves can arise as trajectories of physical test bodies. We explicitly derive autoparallels as effective post-Riemannian geometric constructs, and at the same time we argue against postulating autoparallels as fundamental equations of motion for test bodies in alternative gravity theories.
