Minimum-dimension trace maps for substitution sequences Academic Article uri icon


  • We construct trace maps for products of 2\ifmmode\times\else\texttimes\fi{}2 matrices generated by arbitrary substitution sequences. The dimension of the underlying space of our trace map is the minimal possible, namely 3r-3 for an alphabet of size r\ensuremath{\ge}2.
