To show that the map f ( x n ,r ) = -r + x - x 2 undergoes tangential bifurcation at the origin when x = 0 . To show that for small and positive r, it typically takes many iterations to pass through the bottleneck. To find out how N(r) scales as r → 0 ; to show that at the origin f 2 looks like a rescaled version of f; also to show that it takes approximately N(r) 2 iterations for orbits of f 2 to pass through the bottleneck, where N(r) is number of iterations required to pass through the bottleneck. By expanding f 2 ( x,r ) and neglecting higher order terms, it is to be shown that f 2 ( X,R ) ≅ -R + X - X 2 , and this renormalization implies that N(r) 2 ≈ N ( 4r ) To show that the equation in (d) has the solution N(r)= ar b and solve for b. Concept Introduction: Renormalization is based on the self-similarity of the Figtree- the twigs look like the earlier branches, except they are scaled down in both x and r directions. The Figtree structure shows an endless repetition of the same dynamical processes – a 2 n -cycle is created; it becomes superstable and loses stability in a period doubling bifurcation. Self-similarity is mathematically expressed as comparing f with second iterate f 2 at corresponding values of r and then renormalizing one map into the other. The function f can be renormalized by taking its second iterate, rescaling x → x α , and shifting the value of r to next superstable value. The functional equation for g(x) is g(x) = αg 2 ( x α ) Here, α is universal scale factor, and g(x) is defined in terms of itself.
