Approximate Lie Symmetry Conditions of Autoparallels and Geodesics

Abstract EN

This paper is devoted to the study of approximate Lie point symmetries of general autoparallel systems.

The significance of such systems is that they characterize the equations of motion of a Riemannian space under an affine parametrization.

In particular, we formulate the first-order symmetry determining equations based on geometric requirements and stipulate that the underlying Riemannian space be approximate in nature.

Lastly, we exemplify the results by application to some approximate wave-like manifolds.
