AI中文摘要：
我们给出了一个精确解，描述了四维爱因斯坦-麦克斯韦-伸缩子理论中的多旋转黑洞，它可通过维数约化从五维卡鲁扎-克莱因理论得到。该解表示一个多中心的旋转黑洞构型，带有电荷和磁荷，每个黑洞具有非对齐角动量。这项工作将我们之前对齐角动量黑洞的解推广到非对齐角动量的更一般情况。特殊情况包括马朱马达尔-帕帕佩特鲁解、特奥和万最近的多中心旋转黑洞解以及我们之前不等电荷的解。只要每个黑洞的自旋角动量大小保持在某个上限以下，所得时空在视界内外都没有曲率奇点和封闭类时曲线。
英文摘要：
We present an exact solution describing multi-rotating black holes in 4D Einstein-Maxwell-dilaton theory, which can be obtained from 5D Kaluza--Klein theory via dimensional reduction. The solution represents a multi-centered configuration of rotating black holes carrying both electric and magnetic charges, with each black hole possessing a non-aligned angular momentum. This work generalizes our previous solution for black holes with aligned angular momenta to the more general case of non-aligned angular momenta. It includes, as special cases, the Majumdar--Papapetrou solution, the recent multi-centered rotating black hole solutions of Teo and Wan, and our previous solution with unequal electric and magnetic charges. The resulting spacetimes are free of curvature singularities and closed timelike curves, both on and outside the horizons, provided that the magnitude of the spin angular momentum of each black hole remains below a certain upper bound.
