Propagation of dust acoustic waves in multi components plasma with random parameters,

Abstract In this article, contrary to what is known previously, a randomized dusty plasma
model is introduced. In this newissue, the uncertain properties of the plasma nonlinear system
are assumed as continuous random variables. Hence, a comprehensive probabilistic behavior
of the interesting characteristics of the dusty plasma wave is presented through computing
the first probability density functions and consequently the means, the variances and the
confidence intervals. For this goal, a probabilistic transformational technique that is known
as the random variable transformation is implemented. The obtained theoretical findings are
investigated via some numerical results that showed acceptable consistency with the physical
situations.
