Iterations of real function xn+1 = f( xn ) = xn2 + c
Friday, 23 May 2008 02:14
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.
 
The Third level Bulbs Symmetry
Friday, 23 May 2008 02:10

For the Third level bulbs we have ( m1 / n1 m2 / n2 m3 / n2 ) index. Here you can see ( 1/3 1/4 1/5 ) bulb. It has three different regions in his "antenna" with 3, 4 and 5 spokes (in the square region)

 
The Secondary Bulbs Symmetry
Friday, 23 May 2008 02:07

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 / n1 m2 / n2 ). Note that period of a secondary bulb is n1 x n2 product. In this way we can map all the M-set decorations.
