Dynamical dimension and shift embeddability without the marker property
arXiv:2607.27880
The paper computes the mean dimension and dynamical dimension of a specific aperiodic inverse‑limit system (both equal to N) and shows that, despite lacking the marker property, it can be equivariantly embedded into a cubical shift of alphabet dimension 3N+2; it also proves that the dynamical dimension of a full shift equals the covering dimension of its alphabet.
Abstract
We study the aperiodic inverse-limit system constructed in our earlier work as an example of a finite-mean-dimensional dynamical system without the marker property. We prove that its mean dimension and Meyerovitch's dynamical dimension are both equal to . Despite the absence of the marker property, the system admits an equivariant topological embedding into the cubical shift with alphabet dimension . As an auxiliary result, we prove that the dynamical dimension of the full shift over any compact metrizable alphabet is exactly the covering dimension of the alphabet, including when this dimension is infinite.
