论文摘要
黑洞和buchdahl恒星分别通过$φ（r）= 1/2，4/9 $确定，其中$ g_ {tt} =1-2φ（r）$用于球形对称的静态度量。当一个参与物体被充电和/或旋转时，我们研究了黑洞和buchdahl恒星的最大力，而另一个参与物体则是中性的和无旋转的。事实证明，在通常的四个维空间中，两个schwarzschild对象之间的最大力是通用的，它的光的基本恒定速度和一般相对性（GR）中的重力常数（GR）给出。通常，此功能唯一地挑选了纯Lovelock重力（只有一个$ n $ th订单项，其中包括线性顺序中的GR $ n = 1 $）和尺寸频谱，$ d = 3n+1 $，其中$ n $是Lovelock多项式操作的程度。
Black hole and Buchdahl star are identified respectively by $Φ(R)=1/2, 4/9$ where $g_{tt}=1-2Φ(R)$ for a spherically symmetric static metric. We investigate the maximum force for black hole and Buchdahl star when one of the participating objects is charged and/or rotating while the other is neutral and non-rotating. It turns out that the maximum force between two Schwarzschild objects is universal, given in terms of the fundamental constant velocity of light and the gravitational constant in general relativity (GR) in the usual four dimensional spacetime. In general this feature uniquely picks out the pure Lovelock gravity (having only one $N$th order term in action which includes GR in the linear order $N=1$) and the dimensional spectrum, $D=3N+1$, where $N$ is degree of the Lovelock polynomial action.
