Figure 4From: Bifurcation analysis of a two-dimensional discrete Hindmarsh–Rose type model(a) Bifurcation diagram of map (3) in \((\delta ,x)\) plane for \(a=2\), \(b=2\), \(c=1\), \(d=5.71441 \). The initial value is \((-0.8,-1)\). (b) Local amplification corresponding to (a) for \(\delta \in [0.455, 0.463]\). (c) Maximum Lyapunov exponents corresponding to (a). (d) Local amplification corresponding to (c)Back to article page
