Summary
By definition, BiLipschitz mappings distort distances of points by at most a fixed constant.
Therefore a'priori they are the simplest geometric deformations.
On the other hand, it turns out that even in two dimensions these maps provide a surprisingly rich geometric structure. In particular, in this talk I wish to discuss the multifractal and deformation properties of BiLipschitz mappings.
