Higher Order Non-Planar Electrostatic Solitary Potential in a Streaming Electron-Ion Magnetoplasma: Phase Plane Analysis

We investigate cylindrical and spherical solitons in electron-ion (EI) plasma that contains hot (cold) electrons with stationary ions. The magneto-hydrodynamic equations are solved the aid of reductive perturbation (RP) technique, leading to modified Korteweg–De Vries (mKdV) equation for non-linear behaviour solitary waves EI plasma. By employing reduced differential transform method (RDTM), an approximate solution mKdV is obtained waves. Phase plane analysis reveals these excitations exhibit periodic oscillations. phase model studied.
