I recently got to know about the logistic map, given by $f(x) = rx(1-x)$, and it’s bifurcation diagram when mapped as $r$ along the x-axis.
At $r=3.56995 (approx.)$ we enter the chaotic part with some islands of stability.
All this continues till $r=4$.
But what about $r>4$. Why doesn’t the diagram include it?
What type of behaviour is observed after $r>4$? Does the map become more chaotic or something else happens?
Please help in explaining it to me.
Edit: I checked about it on Google but couldn’t find anything!
