Consistency of dust solutions with div H=0
Research output: Contribution to journal › Article › peer-review
One of the necessary covariant conditions for gravitational radiation is the vanishing of the divergence of the magnetic Weyl tensor Hab, while Hab itself is nonzero. We complete a recent analysis by showing that in irrotational dust spacetimes the condition div H=0 evolves consistently in the exact nonlinear theory.
