  • Curvature measures are an important tool in geometric measure theory and other fields of mathematics for describing the geometry of sets in Euclidean space. But the â��classicalâ�� concepts of curvature are not directly applicable to fractal sets. In order to bridge this gap between geometric measure theory and fractal geometry by introducing a notion of curvature for fractals. For compact sets (e.g. fractals), for which classical geometric characteristic such as curvatures is not available, this notions for their â��parallel sets * ( ) + are studied instead, expecting that their limiting behaviour as does provide information about the structure of the initial set . In particular, the limiting behaviour of the total curvatures (or intrinsic volumes) ( ), , are investigated as well as weak limits of the corresponding curvature measures ( ) as . This leads to the notions of fractal curvature and fractal curvature measure, respectively. The wellâ��known Minkowski content appears in this concept as one of the fractal curvatures. For certain classes of selfâ��similar sets, results on the existence of (averaged) fractal curvatures are presented. These limits can be calculated explicitly and are in a certain sense â��invariantsâ�� of the sets, which may help to distinguish and classify fractals. Based on these results also the fractal curvature measures of these sets are characterized.
