Develops a new theory of fractal dimension using the topological concept of a fractal structure

Provides a rigorous description of the first-known (and currently, the only) general algorithm for calculating the Hausdorff dimension in applications

Shares detailed theoretical results to generalize the classical fractal dimensions, namely, both the box-counting and the Hausdorff dimensions
