SYMMETRY CLASSIFICATION AND INVARIANTCHARACTERIZATION OF TWO-DIMENSIONALGEODESIC EQUATIONS

摘要

We present the point symmetry classification and invariant characterization of a system of two geodesic equations Previously, Aminova and Aminov1 attempted the point symmetry classification. However, they did not identify the Lie algebras nor did they provide an invariant characterization, in terms of coefficients, of the geodesic equations In this paper we do both.
