Abstract :
The amplitude modulation of three-dimensional
(3D) dust ion-acoustic wave (DIAW) packets is studied in
a collisionless magnetized plasma with inertial positive
ions, superthermal electrons and negatively charged
immobile dust grains. By using the reductive perturbation
technique, a 3D-nonlinear Schro¨dinger equation is derived,
which governs the slow modulation of DIAW packets.
