Coboundaries and eigenvalues of morphic subshifts
Coboundaries and eigenvalues of morphic subshifts
We define a morphic subshift as a subshift generated by the image of a substitution subshift by another substitution. In other words, it is the subshift associated with a ultimately periodic directive sequence. We present an efficient algorithm for computing eigenvalues of morphic subshifts using coboundaries. We show that continuous …
