Abstract
Simple conditions are presented under which the fractal dimension of a random walk on an aggregate, dw, is given by dw=D+1, where D is the aggregate's fractal dimension. These conditions are argued (with one simple speculative assumption) to apply for D<2, implying a breakdown of the Alexander-Orbach rule dw=3D2. Existing results for percolation clusters, lattice animals, and diffusion-limited aggregates seem to favor our new rule.
