Investigations of solutions of Einstein's field equations close to lambda-Taub-NUT

Understand

We present investigations of a class of solutions of Einstein's field equations close to the family of lambda-Taub-NUT spacetimes.

• The studies are done using a numerical code introduced by the author elsewhere.
• One of the main technical complication is due to the S3-topology of the Cauchy surfaces.
• Complementing these numerical results with heuristic arguments, we are able to yield some first insights into the strong cosmic censorship issue and the conjectures by Belinskii, Khalatnikov, and Lifschitz in this class of spacetimes.
