B-t bifurcation

WebApr 16, 2014 · Based on the above analysis, we can see that the dynamics of B-T bifurcation can broadly fall into three types between different regions and curves: unstable virus equilibrium, no virus equilibrium, and no limit cycle; stable virus equilibrium; stable virus equilibrium and unstable limit cycle. WebThe codimension-2 bifurcation point, Bogdanov-Takens (BT) bifurcation, which is related to codimension-1 bi- furcations such as the SN bifurcation, homoclinic orbit (Hom) bifurcation, and Hopf bifurcation, is suggested to be related to switch between type I and II excitabil- ities. In some Refs.
