In this project, we investigate the combinatorial and topological structure of tiling spaces, as well as related lattice problems. Tiling spaces are typically obtained as the hull of one or several tilings under the action of the translation group. In particular, we study the close relations between the combinatorial and geometric properties of the individual tilings, the topological properties of the tiling space, and the properties of the dynamical system under the translation action.
