Homeomorphisms between tiling spaces
Abstract: Tiling spaces and tiling groupoids provide higher-dimensional analogues
of subshifts. In this talk, I will investigate what happens when two
tiling spaces are homeomorphic (in subshifts terms: "what happens when
two $Z^d$-subshifts are flow-equivalent.
It generalizes some aspects of the study of flow-equivalence by Parry in
one dimension. It can also be related to Clark and Sadun's theory of
tilings deformations (of which I will give a groupoid interpretation).
