Abstract Stability of a dust acoustic wave in cylindrical complex plasmas is investigated. Effects of a static magnetic field (axial) and an electric field (radial) on the propagation of a low frequency wave are studied. The linear dispersion relations of rotational modes and breathing modes are derived. When a dusty plasma is confined in a finite region, the void behavior is observed at high speed rotation. Vivid structures of different-mode-number solutions are illustrated.
