" It is not time or opportunity that is to determine intimacy – it is disposition alone. Seven years would be insufficient to make some people acquainted with each other, and seven days are more than enough for others. "-Sense & Sensibility, by Jane Austen. Sex has always been a topic of interest for the popular media where stories of promiscuous young adults and celebrity pregnancies stimulate...

Extreme Bowen-York initial data

The Bowen-York family of spinning black hole initial data depends essentially on one, positive, free parameter. The extreme limit corresponds to making this parameter equal to zero. This choice represents a singular limit for the constraint equations. We prove that in this limit a new solution of the constraint equations is obtained. These initial data have similar properties to the extreme Ker...

Generalized Bowen–York Initial Data

A class of vacuum initial-data sets is described which are based on certain expressions for the extrinsic curvature first studied and employed by Bowen and York. These expressions play a role for the momentum constraint of General Relativity which is analogous to the role played by the Coulomb solution for the Gauss-law constraint of electromagnetism.
