Abstract : In this paper we have studied both linear and the nonlinear propagation of electrostatic waves in magnetized homogeneous collisionless dust-ion plasma containing Boltzmann distributed ions and highly charged streaming dust grains. From the numerical study of the linear dispersion relation it is shown that for a given wave number the wave frequency increases with increase in the streaming velocity of dust particles but the wave frequency decreases with the increase in obliqueness of the wave propagation. To study the nonlinear behavior of the wave we have derived an energy integral equation by using Sagdeev pseudo potential technique. Effects of dust streaming and obliqueness of propagation on the condition of formation and profile of possible solitary wave structure have also been numerically analyzed and discussed.
