Petrov type I silent universes with G3 isometry group: the uniqueness result recovered
Wylleman, Lode · Bergh, Norbert Van den
Original · EN
The silent universe conjecture (Sopuerta 1997, van Elst et al. 1997) states that the only algebraically general silent universes are the orthogonally spatially homogeneous Bianchi I models. In the same paper by Sopuerta this was confirmed for the subcase where the spacetime also admits a group G3 of isometries. However the proof contains a conceptual mistake. We recover the result in a different way.
