TITLE: Period doubling is chaos?
QUESTION [5 upvotes]: I've already read something about chaos and it's origins but I am not sure that this affirmative statement is true for all the cases. Can anyone help me? Thanks, Bruno

REPLY [2 votes]: Bifurcation theory refers to the branching of solutions at some critical value parameter, which results in a loss of structural stability.
Bifurcation is one of the routes to chaos.
A few main ruotes to chaos are period doubling, intermittency, horseshoes and homoclinic orbits.
You can look at the Logistic Map for an example of where period doublings can lead to chaos.
