摘要：
The motion of stars in galactic disks is considered in the epicyclic approximation in a potential derived from gauge gravitation theory. It is assumed that the instability of circular orbits of stars with respect to small perturbations in such a potential can lead to the formation of spiral arms. We find the values of the unknown coefficients from the lagrangian of gauge gravitation theory such that they allow such an instability to occur.
