On the Study of the Substructure of N-body Systems
K. M. Bekarian, A. A. Melkonian
Statistical properties of nonlinear systems revealed in an unexpected way already in Fermi-Pasta-Ulam paper, are responsible for the appearance of substructures. We represent a met…

On the Stability of Stellar Systems with Double Massive Centre
K. M. Bekarian, A. A. Melkonian
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…

Parametric S-tree Method and Its Generalizations
Karen M. Bekarian, Anahit A. Melkonian
A parametric approach is developed to the method of S-tree diagrams and its generalization for investigation of the hierarchical substructure of -body nonlinearly interacting sy…
