Consistency of dust solutions with div H=0
Roy Maartens, William Lesame, George Ellis
One of the necessary covariant conditions for gravitational radiation is the vanishing of the divergence of the magnetic Weyl tensor H_{ab}, while H_{ab} itself is nonzero. We comp…
Integrability of irrotational silent cosmological models
H van Elst, C Uggla, W Lesame +2
We revisit the issue of integrability conditions for the irrotational silent cosmological models. We formulate the problem both in 1+3 covariant and 1+3 orthonormal frame notation,…
Irrotational dust with Div H=0
W. M. Lesame, G. F. R. Ellis, P. K. S. Dunsby
For irrotational dust the shear tensor is consistently diagonalizable with its covariant time derivative: , if and only if the divergence of the mag…
