Self-affine fractals: deterministic and random constructions

Abstract

This thesis is a study of dimensional properties of deterministic and random self-affine sets. Strictly self-affine sets (deterministic constructions) are considered in Chapter 1, while Chapter 2 deals with statistically self-affine sets (random constructions).In Chapter 1 we consider self-affine sets generated by affine transformations S1,…,SN subject to certain restrictions. The self-affine set is the unique nonempty compact set Λ satisfying Λ = S1(Λ) U…U SN(Λ). We determine the box and Hausdorff dimensions of such sets and give necessary and sufficient conditions for the box dimension to equal the Hausdorff dimension. These same conditions are also necessary and sufficient for the Hausdorff measure of the set to be positive and finite. In most cases these conditions are not satisfied; so typically the two dimensions are not equal and the Hausdorff measure of the set is either zero or infinite. Even though the sets considered in Chapter 1 are deterministic the methods used are la ...
