Propagation of Ion-Acoustic Solitary Waves for Damped Forced Zakharov Kuznetsov Equation in a Relativistic Rotating Magnetized Electron-Positron-Ion Plasma

The purpose of this paper is to determine the nonlinear properties of the ion-acoustic solitary waves (IASW) propagating obliquely, under the influence of external periodic force combining with a damping term in a rotating, weakly relativistic and magnetized electron-positron-ion plasma. Reductive perturbation technique is employed to derive the damped forced Zakharov Kuznetsov (DFZK) equation. Using the momentum conservation law, ion acoustic solitary wave solution is obtained for DFZK equation. Considerable effects are found in the structures of IASW with the variation of the ratio of temperature of electron and positron, concentration of positron, obliqueness, relativity, ion temperature, magnetic field and due to the presence of external forces. Numerical simulations are depicted for clear vision of the propagating properties of IASW.
