Fig. 5

The kink-type solution of Eq.(5.28) is illustrated in the form of 3D surface, 2D profile (fractional derivative impact) and contour representation for different parameter values i.e \(\sigma = 3,\ \delta = 2.5,\ \lambda = -1,\ \rho = 0,\ \alpha = 0.01,\ \theta = 1,\ \tau = 2,\ c = 1,\ \beta = 0.53\), and \(\epsilon = 1\), and \(g_1=1.2\).
