“…Our proof is based on the construction of averaged metric in TOME 59 (2009), FASCICULE 3 Section 2, and on the description of conformal vector fields for Riemannian metrics due to [14,15,18,2,23,13,10,9,19].…”

“…We replace the conformai Riemann tensor in these equations by (16. 9) and (16.10) and then simplify using (11.14) and (14. Now if use is made of (12.12), (12.21) and (11.14), we find that If any Uihw) (,-"+1), <r^(''"'_l)(«»+i) occurring in any of the above equations is replaced by another which differs from it by an additive null solution, the equation remains unchanged and the additional tensors due to the presence of the null tensor must vanish.…”
