  • The logistic map bifurcation diagram can be analytically explained. We calculate the value of first few bifurcation points, where the non-zero fixed point emerges and stable cycles of period 2 and 4 emerge via a period-doubling bifurcation (or flip bifurcation). We see a map version of fixed point ghosts and bottlenecks, regions of high residence time, related to the intermittency route to chaos.

      @@ProfessorRoss much appreciated Ross. I gone through 5 of your lecture today all of them beautifully presented and broke down the way almost anyone can understand it. I am looking to learn more on the dimensional representation of these systems especially in correspondence to physics as gravity related to chaos as far as I see from dynamic perspective. I did some simulations and lattice models related to string theory but tend to think there is something fishy going with correlations between fix points. Seems to me black holes behave like attractors and in my modelling I see some dimensional reduction. Looking forward if you have any lectures on these relationships.
      The duffing oscillator also a nice analogue, especially to the big bang scenario but these are just my speculative assumptions :)
