Abstract |
This talk reviews and gives a historical background to recent developments concerning spacelike singularities in general relativity. The talk consists of two parts. The first part presents mathematically rigorous results about generic singularities in spatially homogeneous cosmology, most notably Bianchi types VIII and IX. The second part describes recent analytical and numerical results concerning generic behavior and so-called recurring spike formation toward a generic spacelike singularity in inhomogeneous cosmology. Both parts of the talk involve connections between asymptotic behavior, hierarchical structures, and solution generating techniques, which provide new hints for the existence of hidden asymptotic symmetries. |
