nLab Hausdorff dimension



Hausdorff dimension is a method of measuring the dimension of a metric space. It is always a non-negative real number, but it need not be an integer; one way to define a fractal is a metric space with a fractional (non-integral) Hausdorff dimension. Hence Hausdorff dimension is an example of fractal dimension.

The Hausdorff dimension of the cartesian space n\mathbb{R}^n (or any inhabited open subset thereof) is nn. The Hausdorff dimension of a self-similar fractal which consists of nn copies of itself reduced in size by a factor of mm is log mn\log_m n.

In general, Hausdorff dimension may be defined using Hausdorff measure?.
