A generalization of Cobham's Theorem
Fabien Durand
If a non-periodic sequence is the image by a morphism of a fixed point of both a primitive substitution and a primitive substitution , then the dominant eigenvalues of t…
A characterization of substitutive sequences using return words
Fabien Durand
We prove that a sequence is primitive substitutive if and only if the set of its derived sequences is finite; we defined these sequences here.
A theorem of Cobham for non-primitive substitutions
Fabien Durand
In this article we generalize Cobham theorem to a large class of substitutions including non primitive and non constant length substitutions.
Words and morphisms with Sturmian erasures
Fabien Durand, Adel Guerziz, Michel Koskas
We say $x \in \{0,1,2 \}^{\NN}$ is a word with Sturmian erasures if for any the word obtained erasing all in is a Sturmian word. A large family of such wo…
