复闵可夫斯基空间世界线的真实意义

The Real Meaning of Complex Minkowski-Space World-Lines

T. M. Adamo, E. T. Newman

摘要:

结合Minkowski空间中无剪切零测地线的研究,我们研究了复Minkowski空间中的复世界线在实Minkowski空间中引起的实几何效应.我们已经知道,在形式上,复闵可夫斯基空间中的复解析曲线诱导无剪切的零测地同余。在这里,我们看看复杂的线和真正的结构的直接几何连接。在其他项目中,我们显示,特别是,如何一个复杂的世界线项目到真正的闵可夫斯基空间的形式,一个真正的剪切自由零测地同余。

英文摘要:

In connection with the study of shear-free null geodesics in Minkowski space, we investigate the real geometric effects in real Minkowski space that are induced by and associated with complex world-lines in complex Minkowski space. It was already known, in a formal manner, that complex analytic curves in complex Minkowski space induce shear-free null geodesic congruences. Here we look at the direct geometric connections of the complex line and the real structures. Among other items, we show, in particular, how a complex world-line projects into the real Minkowski space in the form of a real shear-free null geodesic congruence.
