Block maps between primitive uniform and Pisot substitutions
VILLE SALO, ILKKA TÖRMÄ · Ergodic Theory and Dynamical Systems · 2014
In this article, we prove that for all pairs of primitive Pisot or uniform substitutions with the same dominating eigenvalue, there exists a finite set of block maps such that every block map between the corresponding subshifts is an element of this set, up to a shift.
