The Goldberg-Sachs theorem in linearized gravity
The Goldberg-Sachs theorem has been very useful in constructing algebraically special exact solutions of Einstein vacuum equation. Most of the physical meaningful vacuum exact solutions are algebraically special. We show that the Goldberg-Sachs theorem is not true in linearized gravity. This is a remarkable result, which gives light on the understanding of the physical meaning of the linearized...
متن کاملEditorial note to : Jerome Kristian and Rainer K . Sachs , Observations in cosmology
This paper is one of the least appreciated fundamental papers in theoretical cosmology. It carefully develops a direct observationally based approach to cosmology, in contrast to the standard model-fitting approach; and it does so in a comprehensive and systematic way. However it only does so in the form of a power-series solution (as was the custom at the time in cosmology): later papers have ...
متن کاملOn the Trinomial Arcs J ( p , k , r , n )
We study the trinomial arcs J(p, k, r, n) and we prove the monotonicity of this category of arcs. Mathematics Subject Classification: 26C10, 30C15, 14H45, 26A48
متن کاملA higher-dimensional generalization of the geodesic part of the Goldberg-Sachs theorem
In more than four spacetime dimensions, a multiple Weyl-aligned null direction (WAND) need not be geodesic. It is proved that any higher-dimensional Einstein spacetime admitting a non-geodesic multiple WAND also admits a geodesic multiple WAND. All five-dimensional Einstein spacetimes admitting a non-geodesic multiple WAND are determined.
