We classify all -natural operators transforming projectable-projectable torsion-free classical linear connections on fibered-fibered manifolds of dimension into th order Lagrangians on the fibered-fibered linear frame bundle on . Moreover, we classify all -natural operators transforming projectable-projectable torsion-free classical linear connections r on fiberedfibered manifolds of dimension into Euler morphism on . These classifications can be expanded on...
