Abstract: | The paper is devoted to justification of the potential energy minimum principle in the problem of stability of a uniformly
rotating viscous incompressible self-gravitating liquid. The capillary forces on the free boundary of the liquid are not taken
into account. It is proved that the regime of rigid rotation is stable if the second variation of the energy functional is
positive. The proof is based on the analysis of the evolution free boundary problem for perturbations in the velocity and
pressure of the rotating liquid. Bibliography: 15 titles.
