Planar Rosa: a family of quasiperiodic substitution discrete plane tilings with 2n-fold rotational symmetry

We present Planar Rosa, a family of rhombus tilings with a 2n-fold rotational symmetry that are generated by a primitive substitution and that are also discrete plane tilings, meaning that they are obtained as a projection of a higher dimensional discrete plane. The discrete plane condition is a relaxed version of the cut-and-project condition. We also prove that the Sub Rosa substitution tilings with 2n-fold rotational symmetry defined by Kari and Rissanen do not satisfy even the weaker discrete plane condition. We prove these results for all even n > 4. This completes our previously published results for odd values of n.

Automated summary

Planar Rosa is a family of rhombus tilings with rotational symmetry that are generated by substitution and are also discrete plane tilings. We prove that Sub Rosa substitution tilings with rotational symmetry do not satisfy the discrete plane condition. This research is important for understanding the characteristics of plane tilings.
