Iterations of real function
xn+1 = f( xn ) =
xn2 + c
We begin with this demonstration, where map
f oN(x) = f(f(...f(x))) is the blue curve,
y = x is the green line and -2 < x,y < 2.
C coincides with the Y one because y(0) = f(0) = C.
Dependence xn on n is ploted in the right window.
For the Third level bulbs we have
( m1 / n1m2 /
n2m3 / n2 ) index.
Here you can see ( 1/31/41/5 ) bulb. It has three different regions in his
"antenna" with 3, 4 and 5 spokes (in the square region)
Every ( m1 / n1 )
primary bulb has decoration very similar to the main bulb one (in "square"
parametrisation). So for the secondary bulbs we have simply to add one more
m2 / n2 rotation number
( m1 / n1m2 / n2 ).
Note that period of a secondary bulb is n1 x n2
product. In this way we can map all the M-set decorations.
