What mathematics underly fractals?
The areas of geometry, nonlinear dynamics and statistical scaling laws underly fractal structures. Described below are some key mathematical concepts. Fractal Dimension (Hausdorff Dimension) Fractal structures exist between integer dimensions. Instead of describing objects as existing in between 1,2 and 3D space, their complexity is captured as existing between in between these integer dimensions. Fractal dimension = log(number of self-similar pieces)/log(magnification factor
