# Coordinates and boundary conditions for the general relativistic initial data problem

@article{Thornburg1987CoordinatesAB, title={Coordinates and boundary conditions for the general relativistic initial data problem}, author={Jonathan Thornburg}, journal={Classical and Quantum Gravity}, year={1987}, volume={4}, pages={1119-1131} }

Using York's method, the author discusses techniques for numerically constructing GR initial data on a Cauchy surface representing spacetimes containing arbitrary numbers of black holes, each with arbitrary mass, position, (linear) momentum and spin (angular momentum). The initial data slices discussed are maximal and 3-conformally flat. The author restricts the discussion to axisymmetric asymptotically flat vacuum (outside the black holes) slices, although these restrictions are not essential.
