有碰撞和无碰撞Wave Fronts的引力波

Gravitational Waves with Colliding or Non--Colliding Wave Fronts

Peter A. Hogan, Dirk Puetzfeld

摘要:

爱因斯坦真空场方程的精确解模拟了纯引力辐射的引力场,其波前要么是平面的,要么是近似球形的。我们描述了一个计划,旨在明确检查是否波前碰撞。从时空的角度来看,该计划确定是否零超曲面的波前历史相交,特别是,允许容易识别的情况下,零超曲面不相交。

英文摘要:

The known exact solutions of Einstein's vacuum field equations modeling the gravitational fields of pure gravitational radiation involve wave fronts which are either planar or roughly spherical. We describe a scheme designed to check explicitly whether or not the wave fronts collide. From the spacetime point of view the scheme determines whether or not the null hypersurface histories of the wave fronts intersect and, in particular, allows easy identification of the cases in which the null hypersurfaces do not intersect.
