[7] Here and in the following the adjective « Riemannian » will always be understood to occur with the prefix « pseudo », denoting that the signature is not necessarily positive definite.

[9] With only one parameter the invariance of the action requires that the Lagrangean be homogeneous of degree one in the velocities and the Euler identities follow. Now the 4-dimensional space-time manifold is the range of the parameters and we have the Noether identities. They consist of the necessary and sufficient conditions for defining a globally invariant volume element for Riemannian geometry, Ricci's lemma, contracted Bianchi identities and the identically vanishing Hamiltonian tensor. It is this last identity that plays a fundamental role here.

[10] H. Weyl, Ann. Phys., t. 54, 1917, p. 117; T. Levi-Civita, Rend. Accad. dei Lincei, 1917-1919. The generalization which includes rotation is due to many authors, see e. g., J. Ehlers, Thesis, Hamburg; A. Papapetrou, Ann. Phys., t. 12, 1953, p. 309.

[11] This was first recognized by R.A. Matzner and C.W. Misner, Phys. Rev., t. 154, 1967, p. 1229, but as they first imposed a coordinate condition, their metric analogous to our Equation (3) is not the full metric.

[12] One possible generalization, cf. ref. 2, is to take for the two 2-covariant tensors the metric g and the Ricci tensor R on M, whereupon g, R will be Einstein's Lagrangean, but in this case we cannot introduce a metric such as g'.
