Abstract: | We prove the theorem: The second-order quasilinear differential operator as a second-rank divergence-free tensor in the equation
of motion for gravitation could always be derived from the trace of the Bianchi derivative of the fourth-rank tensor, which
is a homogeneous polynomial in curvatures. The existence of such a tensor for each term in the polynomial Lagrangian is a
new characterization of the Lovelock gravity. |
