Fig. 6

The anti-kink type solution of Eq.(5.29) is illustrated in the form of 3D surface, 2D profile (fractional derivative impact) and contour representation for different parameter values i.e \(\sigma = 2,\ \delta = 5,\ \lambda = 1,\ \rho = 0,\ \alpha = 0.11,\ \theta = 2,\ \tau = 5,\ c = 0.3,\ \beta = \frac{1}{2}\), and \(\epsilon = 0.5\), and \(g_1=2\).
