Janis-Newman算法:简化和规范场变换

Janis-Newman algorithm: simplifications and gauge field transformation

Harold Erbin

摘要:

Janis-Newman算法是一种古老但非常强大的工具,可以通过一组复杂的坐标变换从静态解生成旋转解。用这种方法已经导出了几个解,包括具有规范场的解。然而,到目前为止,后者的转变一直被假定为一个临时的结果。在本文中,我们提出了一个推广的过程,将其推广到规范场的变换。由于G.詹皮耶里我们说明我们的处方上的Kerr-Newman解决方案。

英文摘要:

The Janis-Newman algorithm is an old but very powerful tool to generate rotating solutions from static ones through a set of complex coordinate transformations. Several solutions have been derived in this way, including solutions with gauge fields. However, the transformation of the latter was so far always postulated as an ad hoc result. In this paper we propose a generalization of the procedure, extending it to the transformation of the gauge field. We also present a simplification of the algorithm due to G. Giampieri. We illustrate our prescription on the Kerr-Newman solution.
