Web31 de out. de 2024 · As a result, there must be a Hopf bifurcation when β = β 1 ∈ (β 0, β max) or equally . As an example, this theorem can be observe in the plot of Fig 5. It is straightforward to examine that these parameters satisfy the conditions of this theorem, and β 0 = .04 and β max ≈.06154. Obviously, there are two Hopf bifurcations in this case. WebThe three-dimensional Muthuswamy–Chua–Ginoux (MCG, for short) circuit system based on a thermistor is a generalization of the classical Muthuswamy–Chua circuit differential system. At present, there are only partial numerical simulations for the qualitative analysis of the MCG circuit system. In this work, we study local stability and Hopf bifurcations of …
