Figure 4From: Regularization of the fractional Rayleigh–Stokes equation using a fractional Landweber methodA comparison between the exact and regularized solutions of the proposed method (case 1) and according to [19] (case 2) at \(t = 0.1\) for \(\upalpha \in\{0.2; 0.4; 0.6; 0.8\}\), \(\delta=0.001\), and \(N_{x} = N_{t} = 40\)Back to article page
