Dynamics of Julia and Fatou sets
Mandelbrot set carries no dynamics. It is a set of parameter values.
There are no orbits on parameter plane, one should not draw orbits on parameter plane. Orbit of critical point is on the dynamical plane
Julia set it is a dynamical system:
- complex ,
- nonlinear,
- deterministic,
- discrete .
Classifications of periodic points Zp of period n with stability index = Abs(l) = | l|
- super-attracting periodic point , when | ln(Zp )| = 0
super-attracting periodic point can be reached by forward iteration
every super-attracting cycle is contained in Fatou set
- attracting ( but not super-attracting) periodic point, when 0 < | ln(Zp )| < 1
attracting periodic point can be reached by forward iteration
every attracting cycle is contained in Fatou set
- indifferent = neutral periodic point , when | ln(Zp )| = 1 = | e2*Pi*i*angle|
- repelling periodic point , when | ln(Zp )| > 1
repelling periodic point can be reached by backward iteration ( IIM )
Julia sets include cycles of repelling points
------------------------------------------
- hyperbolic , when | ln(Zp )| < > 1
- non-hyperbolic , when | ln(Zp )| = 1= | e2*Pi*i*angle|
- rationally indifferent = parabolic, when angle is rational number
Invariant set is Fatou-Leau flower
every parabolic cycle is contained in Julia set
parabolic parameter is a root point
- irrationally indifferent = elliptic, when angle is irrational number
- linearizable
- semi-linearizable
- non-linearizable
