Figure 6From: Multiple bifurcations and periodic coexistence in a delayed Hopfield two-neural system with a monotonic activation functionThe real parts of system eigenvalues with \(\tau _{1}\) increasing: (a) \(\gamma = - 0.5\) and (b) \(\gamma = 0.5\). The other parameters are \(a _{12} = 1\), \(a _{21} = - 0.6\), and \(\tau _{\mathrm{s}} = 0\)Back to article page
