Figure A10.

“Parabolic amplitude” bursting, a phenomenological variant of fold/homoclinic bursting, with μ₂ = 0.2, ν = −0.132, A = 0.006, ${\stackrel{‒}{\mu }}_1$ = 0.023 and ε = 0.05. This case does not correspond to a path in Figure A1; μ₂ was changed to move both Hopf bifurcations to the right of the left knee (small periodic branch corresponding to the right Hopf bifurcation not displayed).
