Talk:Kasner metric

Special case

 * The Riemann tensor vanishes only when a single $$p_j=1$$ and the rest vanish. This has the interesting consequence that this particular Kasner solution must be a solution of any extension of general relativity in which the field equations are built from the Riemann tensor. []

Eh... if you'll forgive the "original research", if the Riemann tensor vanishes, it's flat, and I provided the co-ordinate transformation. --192.75.48.150 (talk) 15:34, 31 October 2014 (UTC)
