-adic characterization of minimal dendric shifts
France Gheeraert, Julien Leroy
Dendric shifts are defined by combinatorial restrictions of the extensions of the words in their languages. This family generalizes well-known families of shifts such as Sturmian s…

Decidability of the isomorphism problem between multidimensional substitutive subshifts
Christopher Cabezas, Julien Leroy
An important question in dynamical systems is the classification problem, i.e., the ability to distinguish between two isomorphic systems. In this work, we study the topological fa…
