Large normalizers of $Z^{d}$ -odometers systems and realization on substitutive subshifts

Christopher Cabezas, Samuel Petite

For a $Z^{d}$ -topological dynamical system $(X, T, Z^{d})$ , an isomomorphism is a self-homeomorphism $I ¨ : X \to X$ such that for some matrix $M\in {\rm GL}(d,{\m…

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…
