Several models of a layered inhomogeneous elliptical galaxy (EG) having the shape either a triaxial ellipsoid or an oblate or prolate spheroid and consisting of baryonic mass and dark matter with different laws of density distribution—profiles. Based on these models, some key dynamic parameters of the EG. The relationships between the important dynamic parameters of the galaxy have been established. Evolutionary scenarios for the formation of EG were studied according to these models. The equilibrium and stability (instability) of the EG as a dynamic system have been established according to known criteria.
S. A. Gasanov (Mon,) studied this question.
