Figure 4. A comparison between the semi-analytical solution (36) (dashed curve) and (a) the RK4 numerical solution (dotted curve), (b) the FDM numerical solution (dotted curve), and (c) the HPM numerical solution (dotted curve). Here, the values of the physical parameters are subject to the presnt plasma model: α = 0.77 813, β = 0.0721 875, γ = −0.048 633, q0 = 0.1, and ${\dot{q}}_{0}=0.1$.
