Killing张量与对称性

Killing Tensors and Symmetries

David Garfinkle, E. N. Glass

摘要:

本文提出了一种在对称时空中求Killing张量的新方法。该方法被用来找到所有的梅尔文的磁宇宙和史瓦西真空的Killing张量。我们证明它们都是平凡的。该方法比直接求解完整的Killing张量方程需要更少的计算量,并且即使在时空不是代数特殊的情况下也可以使用。

英文摘要:

A new method is presented for finding Killing tensors in spacetimes with symmetries. The method is used to find all the Killing tensors of Melvin's magnetic universe and the Schwarzschild vacuum. We show that they are all trivial. The method requires less computation than solving the full Killing tensor equations directly, and it can be used even when the spacetime is not algebraically special.
