Description
Summary:A multicomponent collisionless magnetized plasma system consisting of cold mobile electron fluid, hot electrons and positrons following the q -nonextensive distribution, and immobile positive ions is considered to study nonlinear propagation of electron acoustic waves. The reductive perturbation technique is used to reduce the basic set of fluid equations to the Laedke–Spatschek equation. By means of Painlevé integrability and Bäcklund transformation, some analytic solutions of the nonlinear evolution equation are presented. Furthermore, the effect of different plasma parameters on the characteristics of the nonlinear waves including single soliton, M -shaped soliton, breather, and periodic and rogue wave-type structures are graphically discussed.
