Trace mapsIn several problems arising in the quasicrystal theory one is faced with the problem of computing as simply as possible the traces of matrices defined by recursion using a substitution scheme. To be more specific, let us take an example.

This means that, for instance, the analysis of a typical intermetallic structure with ≈10. atoms in t
