Abstract
The dispersion characteristics of the low-frequency mode associated with ve rtical oscillations of dust grains in a quasi-two-dimensional dust-plasma c rystal are calculated, taking into account the dependence of the dust charg e on the local sheath potential. It is shown that the equilibrium of the du st grains close to the electrode may be disrupted by large amplitude vertic al oscillations. [S1063-651X(99)05111-9].
