Query: Tiling Iterated Function Systems   This paper presents a detailed symbolic approach to the study of self-similar
tilings. It uses properties of addresses associated with graph-directed
iterated function systems to establish conjugacy properties of tiling spaces.
Tiles may be fractals and the tiled set may be a complicated unbounded subset
of $\mathbb{R}^{M}$.
