Decidability, arithmetic subsequences and eigenvalues of morphic subshifts
Fabien Durand, Valérie Goyheneche
We prove decidability results on the existence of constant subsequences of uniformly recurrent morphic sequences along arithmetic progressions. We use spectral properties of the su…

Decidability of the isomorphism and the factorization between minimal substitution subshifts
Fabien Durand, Julien Leroy
Classification is a central problem for dynamical systems, in particular for families that arise in a wide range of topics, like substitution subshifts. It is important to be able…
