Snic bifurcation
Did you know?
WebWe report three scenarios for the chimera birth: (1) via saddle-node bifurcation on a resonant invariant circle, also known as SNIC or SNIPER, (2) via blue-sky catastrophe, when two periodic orbits, stable and saddle, approach each other creating a saddle-node periodic orbit, and (3) via homoclinic transition with complex multistable dynamics including an … WebUpon passing the SNIC bifurcation point, the growing cell should ‘hop’ onto the limit cycle oscillation, but the speed of the transition is very slow at the bifurcation point. Hence, …

We study dynamical mechanisms responsible for changes of the firing rate during four different bifurcation transitions in the two-dimensional Hindmarsh … WebFurthermore, the bifurcation SNIC was related to class I excitability, and bifurcations SN, SubH, and SupH were related to class II excitability. Transition from class I excitability to class II excitability occurred when case 1 changed to case 2. It should be emphasized that 2 stable nodes corresponding to the resting state appeared in case 2.
