Figure 1From: A finite-difference discretization preserving the structure of solutions of a diffusive model of type-1 human immunodeficiency virusSnapshots of the approximate solutions T, U, and V of (1) for each row at the time \(t=0\), \(t=1\), \(t=3\), and \(t=5\). The parameters employed are \(\lambda =0.1\), \(\beta =2\), \(d=5.05\), \(\kappa =0.03\), \(\delta =0.016\), \(\gamma =3.0\), \(c=20.4\), and \(N=1000\). We let \(\phi _{T} (x)\), \(\phi _{U} (x)\), and \(\phi _{V} (x)\) be as in Example 9. The approximations were calculated using our implementation of (76) in the Appendix, with \(\tau = 0.00001\) and \(h=1\)Back to article page
