摘要: The propagation of both linear and nonlinear dust acoustic waves (DAWs) in an inhomogeneous magnetized collisional warm dusty plasma (DP) consisting Boltzmann ions, nonextensive electrons, inertial particles is investigated. number density gradients all DP components besides the inhomogeneities electrostatic potential initial fluid velocity are taken into account. dispersion relation a modified Zakharov-Kusnetsov (MZK) equation governing three-dimensional DAWs derived. analytical solution MZK reveals creation compressive rarefactive DAW solitons proposed model. It found that inhomogeneity dimension parameter electron affect significantly DAW's amplitude, width, Mach number. relations our findings with some astrophysical situations have been given.
