使用约克的方法,作者讨论了技术的数值构建GR初始数据的柯西曲面表示时空包含任意数量的黑洞,每个任意质量,位置,(线)动量和自旋(角动量)。所讨论的初始数据切片是最大的和3-共形平坦的。作者限制讨论轴对称渐近平坦的真空(黑洞外)切片,虽然这些限制是不必要的。
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.
