A global conformal extension theorem for perfect fluid Bianchi space-times
arXiv:0710.5723 · doi:10.1016/j.aop.2008.07.002
Abstract
A global extension theorem is established for isotropic singularities in polytropic perfect fluid Bianchi space-times. When an extension is possible, the limiting behaviour of the physical space-time near the singularity is analysed.
