Fundamentals of Fractal Theory

Iterating Process

The iterating process begins with a complex function of the form $ z_{n+1} = f(z_n) $. An initial value $ z_0 $ is chosen, and the function is applied iteratively:

\[ z_1 = f(z_0), \quad z_2 = f(z_1), \quad \dots, \quad z_n = f(z_{n-1}). \]

This sequence of values $ \{ z_0, z_1, z_2, \dots \} $ is called the orbit of $ z_0 $.

Behavior of the Orbit

The behavior of an orbit can be classified into three main types based on the iteration process:

Convergence: If the sequence of iterated values $ \{ z_n \} $ converges to a fixed point.
Divergence: If the sequence $ \{ z_n \} $ tends to infinity as $ n \to \infty $.
Periodicity: If the sequence $ \{ z_n \} $ starts repeating itself after a certain number of iterations.

Let's define define the Generalized Mandelbrot and Julia sets for a general exponent $ d $, and later extend the discussion to transcendental functions like sine, cosine, and the exponential function.

Generalized Mandelbrot and Julia Sets

Both the Generalized Mandelbrot and Julia sets are generated by iterating the function:

\[ z_{n+1} = z_n^d + c, \] where $ d \in \mathbb{Q}$ and $ c $ is a complex constant.

Generalized Mandelbrot Set

In the Generalized Mandelbrot set, starting from $ z_0 = 0 $, we iterate the function $ z_{n+1} = z_n^d + c $ for each value of $ c $ in the complex plane. If the resulting sequence of $ z_n $ remains bounded after a set number of iterations, then the point $ c $ belongs to the Generalized Mandelbrot set. If the sequence diverges (i.e., $ |z_n| \to \infty $), then $ c $ does not belong to the set.

Generalized Julia Set

For the Generalized Julia set, we keep $ c $ fixed and iterate the function $ z_{n+1} = z_n^d + c $ for each point $ z_0 $ in the complex plane. If the sequence $ z_n $ remains bounded, the point $ z_0 $ is part of the Julia set corresponding to that specific $ c $. If the sequence diverges, the point $ z_0 $ is not part of the Julia set.

Transcendental Functions

In addition to the polynomial-based function $ f(z) = z^d + c $, this application allows you to explore Julia sets generated by transcendental functions, which are treated similarly to the polynomial case. The key difference lies in the function applied during iteration. These transcendental functions include:

$ f(z) = \lambda \sin(z) $,
$ f(z) = \lambda \cos(z) $,
$ f(z) = \lambda e^z $,

where $\lambda$ is a complex constant similar to $c$ in the polynomial case. These transcendental functions will be examined in greater detail in the corresponding sections of the application.
