Theory
dimension one means here that f maps complex plain to complex plain ( self map )[1]
z + mz^d
Class of functions :[2]
where :
Simplest subclass :
simplest example :
W say that roots of unity, complex points v on unit circle
are attracting directions if :
mz+z^d

Critical orbit and directions for for complex quadratic polynomial and internal angle 1/3
On the complex z-plane ( dynamical plane) there are q directions described by angles:
where :
- is a internal angle ( rotation number) in turns [3]
- d = r+1 is the multiplicity of the fixed point [4]
- r is the number of attracting petals ( which is equal to the number of repelling petals)
- q is a natural number
- p is a natural number smaller then q
Repelling and attracting directions [5] in turns near alfa fixed point for complex quadratic polynomials

1/2 | 1/4, 3/4 | 0/2, 1/2 |
1/3 | 1/6, 3/6, 5/6 | 0/3, 1/3, 2/3 |
1/4 | 1/8, 3/8, 5/8, 7/8 | 0/4, 1/4, 2/4, 3/4 |
1/5 | 1/10, 3/10, 5/10, 7/10, 9/10 | 0/5, 1/5, 2/5, 3/5, 4/5 |
