Causality in scalar-Einstein waves
arXiv:0903.4138
Abstract
A wavelike scalar-Einstein solution is found and indicating vectors constructed from the Bel-Robinson tensor are used to study which objects co-move with the wave and whether gravitational energy transfer is null.
arXiv commentTitle changed from "A scalar-Einstein wave" to "Causality in scalar-Einstein waves". Was 4 pages is now 9. All material concerning the Bel-Robinson tensor corrected and much expanded. The new solution remains the same
