Abstract

A family of sets {F-d}(d) is said to be 'represented by the measure mu' if, for each d, the set F-d comprises those points at which the local dimension of mu takes some specific value (depending on d). Finding the Hausdorff dimension of these sets may then be thought of as finding the dimension spectrum, or multifractal spectrum, of mu. This situation pertains surprisingly often, with many familiar families of sets representable by measures which have simple dimension spectra. Examples are given from Diophantine approximation, Kleinian groups and hyperbolic dynamical systems.
