AI 中文摘要
我们研究具有混合对称性的高阶广义Killing张量,并给出了一些例子和应用。结果表明,这类对象自然存在于高维旋转黑洞时空中,它们是Killing-Yano张量的部分收缩“平方”,具有有趣的代数和微分性质。受共形Killing张量的启发,提出了一种能沿类光测地线产生平行输运张量的推广,并证明其存在于高维旋转黑洞时空中。
英文摘要
We study higher-rank generalized Killing tensors with mixed symmetries, providing a couple of examples and applications. It is shown that such objects naturally exist in higher-dimensional rotating black hole spacetimes, where they arise as partially contracted "squares" of Killing-Yano tensors and display interesting algebraic and differential properties. Motivated by conformal Killing tensors, a generalization of these objects that gives rise to parallel-transported tensors along null geodesics is proposed and shown to exist in higher-dimensional rotating black hole spacetimes.
