Lie symmetries of the canonical geodesic equations for four-dimensional Lie groups

Ryad Ghanam and Gerard Thompson

For each of the four-dimensional indecomposable Lie algebras the geodesic equations of the associated canonical Lie group connection are given. In each case a basis for the associated Lie algebra of symmetries is constructed and the corresponding Lie brackets are written down.
