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. WebHopf bifurcation. Many studies have shown that these bifurcations are supercritical, but, by using simulations in a comoving frame of reference, we present numerical results which show that subcritical bifurcations are also present within FitzHugh-Nagumo.
