Fractals

    Fractals are geometric objects characterised by structure at all scales, exact or statistical selfsimilarity and dimensions that differ depending on the definition and are typically not integers. The work here includes exact expansions for properties of exactly selfsimilar fractals, fractals as a criterion for chaos in relativity, the first experimental observation of fractal conductance fluctuations in semiconductors, and the periodic orbits description of escape from a fractal repeller in the presence of stochastic perturbations.
