Capacity Dimension

A Dimension also called the Fractal Dimension, Hausdorff Dimension, and Hausdorff-BesicovitchDimension in which nonintegral values are permitted. Objects whose capacity dimension is different from theirTopological Dimension are called Fractals. The capacity dimension of a compact MetricSpace is a Real Number such that if denotes the minimum number of open sets of diameterless than or equal to , then is proportional to as . Explicitly,


(if the limit exists), where is the number of elements forming a finite Cover of the relevant MetricSpace and is a bound on the diameter of the sets involved (informally, is the size of eachelement used to cover the set, which is taken to approach 0). If each element of a Fractal is equallylikely to be visited, then , where is the Information Dimension. Thecapacity dimension satisfies


where is the Correlation Dimension, and is conjectured to be equal to the Lyapunov Dimension.
