Summary:

Combinatorial aspects of periodic and aperiodic tilings are investigated, with special emphasis on generalised symmetries and topological invariants. Of particular interest are crystallographically relevant sublattice structures and their generalisations to $\mathbb{Z}$-modules as well as the calculation and the geometric understanding of cohomology and K-groups for tiling spaces.

This project continues the successful work of the project Combinatorial and geometric structure of aperiodic tilings under the direction of Christoph Richard and Michael Baake.
