论文摘要
讨论了基于Fokker-Planck方程的两体弛豫近似中原始黑洞簇的演变。在我们的计算中，我们考虑了带有各种黑洞质量的自我磨碎集群，从$ 10^{ - 4} m _ {\ odot} $最高$ 100 m _ {\ odot} $，总质量$ 10^5 m _ {\ odot} $。此外，我们在集群中心中包括了一个巨大的黑洞，该黑洞确定了其附近密度谱的演化速率。
Evolution of a cluster of primordial black holes in the two-body relaxation approximation based on the Fokker-Planck equation is discussed. In our calculation, we consider the self-gravitating cluster with a wide range of black holes masses from $10^{-4} M_{\odot}$ up to $100 M_{\odot}$ and the total mass $10^5 M_{\odot}$. Moreover, we included a massive black hole in the cluster center which determines the evolution rate of the density profile in its vicinity.
