A General Covariant Stability Theory |
Abstract _ |
In the present work we establish a general covariant theory which can be used to study the stability of any system treated geometrically. Stability conditions are connected to the magnitude of the deviation vector. This theory is a modification of an earlier work by the same authors concerning stability. A comparison between this work and the earlier one is given. The suggested theory can be used to study the stability of planetary orbits, astrophysical configurations and cosmological models. |
