超对称黑洞在五维超引力下必然是旋转的，因此，为了研究远离超对称黑洞的通道，获得非零旋转的非极值黑洞是非常有意义的。在这封信中，我们找到了一个简单的框架来描述五维超重力测量中的非极端旋转黑洞。使用这个框架，我们能够构建一个新的解，描述N=2测量超重力的一般单电荷解，两个旋转参数具有任意值。先前得到的具有两个或三个相等电荷的解在新的框架中也具有更简单的形式，在未测量的N=2超重力中具有三个不等电荷的一般解也是如此。在这些背景下讨论了新的单电荷解的热力学和BPS极限，并讨论了Hamilton-Jacobi方程和Klein-Gordan方程的可分性。
Supersymmetric black holes in five-dimensional gauged supergravity must necessarily be rotating, and so in order to study the passage to black holes away from supersymmetry, it is of great interest to obtain non-extremal black holes that again have non-zero rotation. In this Letter we find a simple framework for describing non-extremal rotating black holes in five-dimensional gauged supergravities. Using this framework, we are able to construct a new solution, describing the general single-charge solution of N=2 gauged supergravity, with arbitrary values for the two rotation parameters. Previously-obtained solutions with two or three equal charges also assume a much simpler form in the new framework, as also does the general solution with three unequal charges in ungauged N=2 supergravity. We discuss the thermodynamics and BPS limit of the new single-charge solutions, and we discuss the separability of the Hamilton–Jacobi and Klein–Gordan equations in these backgrounds.
