Abstract

To develop an origin theory of galactic bulges the gravitational instabilities of oscillation modes (0,3) and (2,2) have been studied on the background of two non-linearly non-stationary models: anisotropic disk-like system and Kamm’s model. For these modes the critical diagrams have been constructed. The instability increments are also found
