Summary edit
That our mapping from the plane into itself is differentiable as a complex function, means that it is differentiable as a real function - that is, that its two components and are differentiable - and that these two components satisfy the Cauchy-Riemann differential equations:
- and
if so, these two numbers are the real and imaginary part of , respectively.
It is this condition that causes the characteristic features of the Mandelbrot and Julia sets for complex iteration. The usual family of iterations can (in coordinate form) be written → (if c = u + iv), and if we here replace the y-coordinate of the function, that is 2xy, by 1.95×xy, the shapes in the Sea Horse Valley become distorted.
This thread-like and tattered look is typical for the real - or non-complex - fractals. For a function which is not, as in this case, the result of a mild interference in a complex function, the picture is often very chaotic, and the colouring can be impossible at most places, because our method of colouring presupposes that the sequences of iteration converge to a finite cycle, and for a non-complex iteration the terminus need not be a finite set. The terminal set is now called an attractor, and attractors can have very surprising shapes. Because of this, such an attractor is known as a strange attractor.
