WebA model map Q for the Hopf-saddle-node (HSN) bifurcation of fixed points of diffeomorphisms is studied. The model is constructed to describe the dy-namics inside an attracting invariant two-torus which occurs due to the pres-ence of quasi-periodic Hopf bifurcations of an invariant circle, emanating from the central HSN bifurcation.

Web16 feb. 2012 · The birth of the Hopf points are advanced in the depressed patients, and delayed in the case of PTSD in comparison to the normal patients as shown in Figure 9 (E–G). Similarly the Hopf point terminates at a much lower k value in the depressed subjects, and at an extremely high value in PTSD subjects in comparison to the normal … WebIn other words, the Hopf map takes us from a point on the 3-sphere to the point its phase circle is “pasted” onto the 2-sphere. Since we can choose to embed the circle S 1 into any class e i S 1 ( α, β) ⊆ S 3, we write the full fibration as S 1 ↪ S 3 → π S 2, where ↪ is fancy math notation for “embed”.
