The operator D=-i(d+d^*), where d^* is the adjoint.
Two nonsingular forms are equivalent over the rationals iff they have the same determinant and the same p-signatures for all p.
J_(nualphabeta)^mu=J_(nubetaalpha)^mu=1/2(R_(alphanubeta)^mu+R_(betanualpha)^mu), where R is the Riemann tensor.
Orthogonal contravariant and covariant satisfy g_(ik)g^(ij)=delta_k^j, where delta_j^k is the Kronecker delta.
