Lie Symmetries of the Canonical Connection: Codimension Two Abelian Nilradical

Abstract

Nouf Almutiben*, Edward L. Boone, Ryad Ghanam and G. Thompson

In this paper we study the Lie symmetries of the canonical connection on Lie groups for the special case when the Lie algebra has a codimension two abelian nilradical. In this particular case, we have only one algebra in dimension four, namely A_4,12 and three algebras in dimension five; namely . For each of these algebras we investigate and classify the symmetry algebra associated with its geodesic equations.
