Box dimension profiles and intermediate dimensions
Abstract
For a non-empty bounded set E⊂Rd, the upper and lower box dimensions of its orthogonal projections are constant onto almost all m-dimensional subspaces. These almost-sure values are called the upper and lower m-box dimension profiles of E, respectively. We study their relationship with intermediate dimensions, which interpolate between Hausdorff and box dimensions by restricting the relative sizes of covering sets. We establish several equivalent characterizations of both quantities and obtain upper and lower bounds for box dimension profiles in terms of intermediate dimensions, with the lower bounds also involving the upper Assouad spectrum. We further derive explicit formulas for the box dimension profiles in terms of the box dimension and the initial growth rate of the intermediate dimensions, under a suitable condition on the quasi-Assouad dimension.
