Abstract (English):
Ground-based and space observations show that the nuclei of many disk-shaped galaxies are significantly offset from their geometric center. This can lead to the excitation of the lopsided mode m=1. To determine the dependence of this effect on the geometry of the system, in this work we have compared a non-stationary disk model with respect to the gravitational instabilities of the lopsided mode N=3; m=1 perturbation. In this work we have also compiled a summary catalog of lopsided disk-shaped galaxies and conducted a statistical analysis of their physical parameters.
