Fractal sets in analysis, spring 2015


Pertti Mattila


10 sp.


Advanced studies


Basic knowledge of measure and integration theory such as the courses "Mitta ja integraali" and "Reaalianalyysi I". "Reaalianalyysi II"  and basic knowledge of Fourier analysis are useful but not necessary.

Easter Holiday 2.-8.4.

Course description

Fractal sets in this course mean both very general (closed or Borel) sets in Euclidean spaces and special fractal sets such as various Cantor-type sets and graphs of continuous nowhere differentiable functions. They play a significant role in mathematical analysis and also in other parts of mathematics and its applications. Constructions and properties, mainly geometric measure theoretic ones, of such sets will be studied.  Possible  topics for the course include  

Hausdorff dimension, Frostman's lemma, Riesz potentials and capacities, and Fourier transform

Minkowski and packing dimensions

Hausdorff dimension, orthogonal projections, and distance sets

Self-similar and self-affine sets

Graphs of continuous functions (e.g., Weierstrass nowhere differentiable function)

Brownian motion

Cantor sets of uniqueness and multiplicity for Fourier series

Besicovitch (or Kakeya) sets and Fourier transform

Peter Jones's version of the travelling salesman theorem

Removable sets for bounded analytic functions
