Singularities in general relativity theory.
Abstract
The problem of determining the nature of singularities in general relativity theory is considered, and various approaches to this problem are reviewed. Different kinds of singularities are distinguished. In some cases, procedures used to study the effect of shock waves on prediction can be modified for studying the effects of singularities. The implications of good or bad behavior of the curvature tensor in the vicinity of a singularity are examined with attention to scalar invariant singularities and nonscalar curvature singularities. This latter category includes the case of plane gravitational waves and tilted universes. It is suggested that singularities in the universe would not be similar to the described singularities since the theory of general relativity is thought to be inadequate at the physical conditions of singularities.
