摘要: Theoretical and numerical studies are performed for the nonlinear structures (explosive, solitons, shock) in quantum electron-positron-ion magnetoplasmas. For this purpose, reductive perturbation method is employed to hydrodynamical equations Poisson equation, obtaining extended Zakharov–Kuznetsov equation. The latter has been solved using generalized expansion obtain a set of analytical solutions, which reflects possibility propagation various structures. relevance present investigation white dwarfs highlighted.
