Around Cobham's theorem

By Elzbieta Krawczyk

Appears in collection : Combinatorics on words / Combinatoire des mots - Week 5

We provide a complete characterisation of automaticity of uniformly recurrent substitutive sequences in terms of the incidence matrix of the return substitution of an underlying purely substitutive sequence. This gives an answer to a recent question of Allouche, Dekking and Queffélec in the uniformly recurrent case.
