Definition

A metric invariant of a subset defined as the infimum of exponents s for which the s-dimensional Hausdorff measure of the set is zero; it quantifies the scaling exponent of coverings and captures fractal size.

Definition

A fractal dimension defined as the critical exponent s at which the s-dimensional Hausdorff measure of a set jumps from infinity to zero; it quantifies the local scaling of measure required to cover the set with arbitrarily small sets.

Definition

The exponent s≥0 for which the s-dimensional Hausdorff measure of a metric set transitions from infinity to zero; a quantitative invariant that captures the fractal scaling of a set by quantifying how covering measure behaves under refinement.
