Iterated function systems

Description

A common construction for fractal sets is to use an iterated function system, or IFS for short. One can associate with an IFS an invariant fractal set, as well as a family of invariant measures. This category includes my work on self-similar and self-affine sets, which includes dimension theory, multifractal analysis, and the study of separation conditions.
