Figure 6From: Dynamical analysis and chaos control of a discrete SIS epidemic modelThe bounded region for the eigenvalues of the controlled model ( 15 ) in the ( p 1 , p 2 ) plane for A=6, d 1 =0.15, d 2 =0.42, r=0.12, λ=0.75 and h=8.2. The blue ∘ line is l 1 . The red ∗ line is l 2 and the black ⋅ line is l 3 .Back to article page
