Figure 1From: A predator–prey model involving variable-order fractional differential equations with Mittag-Leffler kernelNumerical simulation for the prey–predator model via Atangana–Baleanu–Caputo fractional derivative with constant order (2.1) via the numerical scheme given by Eq. (3.22). In (a)–(b) phase portrait and time series \(\mathbf{x}(\tau )\) and \(\mathbf{y}(\tau )\) for \(\epsilon =1\) and \(\varsigma =1\). In (c)–(d) phase portrait and time series \(\mathbf{x}(\tau )\) and \(\mathbf{y}(\tau )\) for \(\epsilon =0.95\) \(\varsigma =0.9\). In (e)–(f) phase portrait and time series \(\mathbf{x}(\tau )\) and \(\mathbf{y}(\tau )\) for \(\epsilon =0.9\) and \(\varsigma =0.95\)Back to article page
