Covers of Tiling Spaces
Franz Gähler, Jianlong Liu, Lorenzo Sadun
We study the ways that one tiling space can be a finite regular cover of another. We classify all of the finite regular covers of a tiling space via its structure as an inverse lim…

New results on tilings via cup products and Chern characters on tiling spaces
Jianlong Liu, Jonathan Rosenberg, Rodrigo Treviño
We study the cohomology rings of tiling spaces given by cubical substitutions. While there have been many calculations before of cohomology groups of such tiling spaces, the in…
