An extension theorem for conformal gauge singularities

General Relativity and Quantum Cosmology 2010-01-07 v3

Abstract

We analyse conformal gauge, or isotropic, singularities in cosmological models in general relativity. Using the calculus of tractors, we find conditions in terms of tractor curvature for a local extension of the conformal structure through a cosmological singularity and prove a local extension theorem.
