%0 Journal Article %T Intersections of moving fractal sets %A Indrek Mandre %A Jaan Kalda %J Physics %D 2013 %I arXiv %R 10.1209/0295-5075/103/10012 %X Intersection of a random fractal or self-affine set with a linear manifold or another fractal set is studied, assuming that one of the sets is in a translational motion with respect to the other. It is shown that the mass of such an intersection is a self-affine function of the relative position of the two sets. The corresponding Hurst exponent h is a function of the scaling exponents of the intersecting sets. A generic expression for h is provided, and its proof is offered for two cases --- intersection of a self-affine curve with a line, and of two fractal sets. The analytical results are tested using Monte-Carlo simulations. %U http://arxiv.org/abs/1307.4242v1
