The quantitative relationships between \(i_{(m)}\) and \(k_{(n)}\) are \(i_{(2)}= k_{(2)}-1\) and \(i_{(1)}=k_{(1)}+1\) and the bifurcation diagrams of system (8) with different values. (a) \(i_{(2)}=2\), the bifurcation diagram of system (8). (b) \(i_{(1)}=2\), the bifurcation diagram of system (8). (c) \(i_{(2)}=4\), the bifurcation diagram of system (8). (d) \(i_{(1)}=3\), the bifurcation diagram of system (8).
