A Hierarchy of Automatic -Words having a Decidable MSO Theory

Vince Bárány (2008)

RAIRO - Theoretical Informatics and Applications

Similarity:

We investigate automatic presentations of -words. Starting points of our study are the works of Rigo and Maes, Caucal, and Carton and Thomas concerning lexicographic presentation, MSO-interpretability in algebraic trees, and the decidability of the MSO theory of morphic words. Refining their techniques we observe that the lexicographic presentation of a (morphic) word is in a certain sense canonical. We then generalize our techniques to a hierarchy of classes of -words enjoying...
