The stability of a rotating gas-dust gravitating disk in the zone of a possible inflection in the angular velocity is examined theoretically. The stability limits are found for a rather wide range of curves in a special model of a dusty, pressure-free medium with the general gravitational field of the galaxy taken into account. Applications to real galaxies are discussed.
