Parameter scaling for the Fibonacci point

Dynamical Systems 2016-09-06 v1

Abstract

We prove geometric and scaling results for the real Fibonacci parameter value in the quadratic family fc(z)=z2+cf_c(z) = z^2+c. The principal nest of the Yoccoz parapuzzle pieces has rescaled asymptotic geometry equal to the filled-in Julia set of z21z^2-1. The modulus of two such successive parapuzzle pieces increases at a linear rate. Finally, we prove a ``hairiness" theorem for the Mandelbrot set at the Fibonacci point when rescaling at this rate.
