Nonlinear Structures In Dusty Plasma

Solitons, Shocks, vortices etc. are considered to be main nonlinear structures arise in different physical situations. Plasma is a nonlinear medium and to develop plasma research, it essential to study nonlinear waves in plasma physics as it is always keeps a nice relation between the theory and experiment / observations. Solitons and solitary waves are formed in plasma when nonlinearity of the medium exactly balances the dispersion. The term soliton is used as they keep their shape intact even after collision and they move as energy packet without changing their shape. So in every field of plasma physics, from laboratory to astro physical and space plasma, to study soliton and other nonlinear wave structures are essential. Dusty plasma is a relatively new branch of plasma physics, when the presence of micron sized dusts grains modifies different nonlinear structures. In this book we have studied the soliton and double layers in dusty plasma by using Reductive Perturbation Method and Nonperturbative approach
