Magic Numbers in the Discrete Tomography of Cyclotomic Model Sets
We report recent progress in the problem of distinguishing convex subsets of cyclotomic model sets Λ by (discrete parallel) X-rays in prescribed Λ-directions. It turns out that for any of these model sets Λ there exists a ‘magic number’ m Λ such that any two convex subsets of Λ can be distinguished by their X-rays in any set of m Λ prescribed Λ-directions. In particular, for pentagonal, octagonal, decagonal and dodecagonal model sets, the least possible numbers are in that very order 11, 9, 11 and 13.
