On Lie algebras associated with a spray

Authors: Manelo Anona ; Hasina Ratovoarimanana

    The Lie algebra of infinitesimal isometries of a Riemannian manifold contains at most two commutative ideals. One coming from the horizontal nullity space of the Nijenhuis tensor of the canonical connection, the other coming from the constant vectors fields independent of the Riemannian metric.
