We show that a set of small box counting dimension can be covered by a H\"older graph from all but a small set of directions, and give sharp bounds for the dimension of the exceptional set, improving a result of B. Hunt and V. Kaloshin. We observe that, as a consequence, H\"older graphs can have positive doubling measure, answering a question of T. Ojala and T. Rajala. We also give remarks on H\"older coverings in polar coordinates and, on the other hand, prove that a Homogenous set of small… 

Quantitative Besicovitch projection theorem for irregular sets of directions

. The classical Besicovitch projection theorem states that if a planar set E with finite length is purely unrectifiable, then almost all orthogonal projections of E have zero length. We prove a

The dimension of the visible part of self-affine sets, that satisfy domination and a projection condition, is being studied. The main result is that the assouad dimension of the visible part equals

Normal numbers are not fat for doubling measures

Regularity of almost-surely injective projections in Euclidean spaces

. It is known that if a finite Borel measure µ in a Euclidean space has Hausdorff dimension smaller than a positive integer k , then the orthogonal projection onto almost every k -dimensional linear

FAT AND THIN SETS FOR DOUBLING MEASURES IN EUCLIDEAN SPACE

According to the size of sets for doubling measures, subsets of R n can be divided into six classes. Sets in these six classes are respectively called very thin, fairly thin, minimally thin,

Hausdorff dimension and doubling measures on metric spaces

Vol′berg and Konyagin have proved that a compact metric space carries a nontrivial doubling measure if and only if it has finite uniform metric dimension. Their construction of doubling measures

Existence of doubling measures via generalised nested cubes

Working on doubling metric spaces, we construct generalised dyadic cubes adapting ultrametric structure. If the space is complete, then the existence of such cubes and the mass distribution principle

Ergodic fractal measures and dimension conservation

Abstract A linear map from one Euclidean space to another may map a compact set bijectively to a set of smaller Hausdorff dimension. For ‘homogeneous’ fractals (to be defined), there is a phenomenon

We consider sets in uniformly perfect metric spaces which are null for every doubling measure of the space or which have positive measure for all doubling measures. These sets are called thin and

Patterns in random fractals

We characterize the existence of certain geometric configurations in the fractal percolation limit set $A$ in terms of the almost sure dimension of $A$. Some examples of the configurations we study

Regularity of embeddings of infinite-dimensional fractal sets into finite-dimensional spaces

We consider the image of a fractal set X in a Banach space under typical linear and nonlinear projections into N. We prove that when N exceeds twice the box-counting dimension of X, then almost every
