标题： Nonlinear wave equations for numerical relativity: towards the computation of gravitational wave forms of black hole binaries

摘要： LIGO/VIRGO引力波源的主要候选者是致密双星中的黑洞和中子星的并合。虽然致密双星演化的早期阶段可以通过后牛顿近似计算得出，但预测其晚期阶段则需要大规模数值模拟。 本文描述了一种完全协变且严格双曲的数值相对论表述，并通过三维环面上Gowdy波的一维计算进行了说明。该表述允许以完全一般的方式进行叶分解，特别是对拉伸函数没有任何限制。 显示英文摘要

摘要： The prime candidate of LIGO/VIRGO sources of gravitational waves is the spiral in of black holes and neutron stars in compact binaries. While the early stages of the evolution of compact binaries is computable from post-Newtonian calculations, prediction of their late stages requires large scale numerical simulation. A fully covariant and strictly hyperbolic formulation for numerical relativity is described, and illustrated in a one-dimensional computation of a Gowdy-wave on the three-torus. This formulation allows foliations in full generality, in particular it poses no restriction on the lapse function.
