Construction of Solitary Wave Solutions to the (3 + 1)-Dimensional Nonlinear Extended and Modified Quantum Zakharov–Kuznetsov Equations Arising in Quantum Plasma Physics

Several types of solitary wave solutions (3 + 1)-dimensional nonlinear extended and modified quantum Zakharov–Kuznetsov equations are established successfully via the implantation three mathematical methods. The concerned models have many fruitful applications to describe waves in electron–positron–ion magnetoplasmas weakly ion-acoustic plasma. derived results MEAEM method, ESE F-expansion been retrieved will be expedient future illuminate collaboration between lower waves. For physical behavior models, some plotted graphically 2D 3D by imparting particular values parameters under given condition at each solution. Hence explored profitable rewards field physics.
