Figure 3From: Sensitivity and uncertainty analysis of a simplified Kirschner-Panetta model for immunotherapy of tumor-immune interaction The eigenvalue of Jacobian matrix at the positive equilibrium varies as \(\pmb{s_{1}}\) increases. The three solid lines represent the eigenvalues at the large equilibrium \((x_{1},y_{1},z_{1})\), and the other three dash-dot lines represent the eigenvalues at the small equilibrium \((x_{2},y_{2},z_{2})\).Back to article page
