40 === Course description ===
41
42 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 
43
44 Hausdorff dimension, Frostman's lemma, Riesz potentials and capacities, and Fourier transform
45
46 Minkowski and packing dimensions
47
48 Hausdorff dimension, orthogonal projections, and distance sets
49
50 Self-similar and self-affine sets
51
52 Graphs of continuous functions (e.g., Weierstrass nowhere differentiable function)
53
54 Brownian motion
55
56 Cantor sets of uniqueness and multiplicity for Fourier series
57
58 Besicovitch (or Kakeya) sets and Fourier transform
59
60 Peter Jones's version of the travelling salesman theorem
61
62 Removable sets for bounded analytic functions
