标题： On the Stability of Stellar Systems with Double Massive Centre

摘要： 里奇曲率判据被用于研究N体引力系统几种构型的相对不稳定性。结果显示，具有双质量中心的系统比均匀系统以及单一大质量中心的系统更不稳定。总体而言，这表明古扎迪安和科恰良（1987年）引入的里奇曲率方法对于通过相对简单的计算（即小的N值，因此需要较少的计算机资源）来研究N体系统是有效的。 显示英文摘要

摘要： The Ricci curvature criterion is used for the investigation of the relative instability of several configurations of N-body gravitating systems. It is shown, that the systems with double massive centers are more unstable than the homogeneous systems and those with one massive center. In general this shows the efficiency of the Ricci curvature method introduced by Gurzadyan and Kocharyan (1987) for the study of N-body systems via relatively simple calculations, i.e. for small N, and hence small computer resources.
