2.4: Iterations of inverse quadratic maps

( \newcommand{\kernel}{\mathrm{null}\,}\)

Repelling periodic orbits are dense on the Julia set. They become attracting if we iterate inverse function

    fc -1 = ±(z - c)½,

therefore we can use iterations of the map to plot the J set to the right below.

Douady's Rabbit, Dendrite and Cantor dust Julia sets illustrate inverse iterations. In this script the sign of z½ is chosen at random. Points are gathered at the outer border of J and its inner structure is vague.
