Description

A new anisotropic nonstationary model of a self-gravitating disk-shaped system has been constructed to study instability of asymmetric and U-shaped oscillation modes through the given model. Nonstationary analog of the dispersion relation of new anisotropic model has been obtained for the vertical warp modes. The instability increments for warp oscillation modes have been calculated as functions of the initial value of the virial ratio. (authors)
