Let μ : F X X be a principal bundle of frames with the structure group Gl n ( ) . It is shown that the variational problem, defined by Gl n ( ) -invariant Lagrangian on J r F X , can be equivalently studied on the associated space of connections with some compatibility condition, which gives us order reduction of the corresponding Euler-Lagrange equations.
