Qualitative and Computational Analysis of a Mathematical Model for Tumor-Immune Interactions
shows the bifurcation diagrams for the bilinear model (2.5) for the parameter : [—] represents the stable equilibrium, [- - -] represents the unstable equilibrium, [⋯] is the stable limit cycles, while [∘] is the saddle node bifurcation. [•] is the transcritical bifurcation and [□] the supercritical Hopf bifurcation. The values of parameters are given in Table 1.
