JuliaSetBoettcher

JuliaSetBoettcher[c,z]

gives the Böttcher coordinate of z with respect to the quadratic Julia set Jc.

Details and Options

  • The Julia set of a function f is the closure of the set of all repelling fixed points of f.
  • The Böttcher function is given by and satisfies the conjugacy .
  • With the option MaxIterations->m, the sequence will be iterated at most m times to approximate .
  • The default setting is MaxIterations->100.
