ABDELSALAM, U. M.. Nonlinear dynamical properties of solitary wave solutions for Zakharov-Kuznetsov equation in a multicomponent plasma. Rev. mex. fis. [online]. 2021, vol.67, n.6, 061501.  Epub 14-Mar-2022. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.67.061501.

Using the reductive perturbation method, we have derived the Zakharov-Kuznetsov equation for a multi-component plasma model consisting of electrons, positrons, and fluid ions with positive and negative charges. The extended homogenous balance method has been applied to obtain the soliton solution in addition to many traveling wave solutions. Various physical parameters have different effects on the profile of the solitary wave pulses, which can show the propagation of the ion, acoustic waves in laboratory plasmas and many astrophysical plasma systems as in Earth’s ionosphere.

Palabras llave : Zakharov-Kuznetsov (ZK) equation; multicomponent plasma; ion-acoustic solitary waves; HB method; nonlinear partial differential equations.
