Scaling of Fronts in Gradient Percolation — •Alex Hansen — Inst. for fysikk, NTNU, Trondheim, Norway

Recent advances in uncovering the intricacies of the scaling properties of fracture surfaces have necessitated a careful rethinking of concepts that by now should have been quite well understood: fractals, self affinity, multiaffinity, multifractals. We use the well-studied example of percolation in a gradient in the occupation probability to clarify the concepts. We then proceed to describe fracture surfaces using these concepts.
