The analysis begins by structural considerations: quasiperiodic tilings. To any set of tiles that tiles the plane, we associate a quasiperiodicity function that quantifies complexity. Firstly, it is shown that any "reasonable" function may be captured by a set of tiles and that there are tilings whose quasiperiodicity function grows faster than any computable function. Then we prove a Rice theorem for tilings: the set of all tile sets that recognize the same tilings as another tile set is recursively enumerable and undecidable. Finally, we transpose our results in th...
