# Application of signal analysis to the embedding problem of $${\mathbb {Z}}^k$$Zk-actions

@article{Gutman2017ApplicationOS, title={Application of signal analysis to the embedding problem of \$\$\{\mathbb \{Z\}\}^k\$\$Zk-actions}, author={Yonatan Gutman and Yixiao Qiao and Masaki Tsukamoto}, journal={Geometric and Functional Analysis}, year={2017}, pages={1-63} }

We study the problem of embedding arbitrary $${\mathbb {Z}}^k$$Zk-actions into the shift action on the infinite dimensional cube $$\left( [0,1]^D\right) ^{{\mathbb {Z}}^k}$$[0,1]DZk. We prove that if a $${\mathbb {Z}}^k$$Zk-action X satisfies the marker property (in particular if X is a minimal system without periodic points) and if its mean dimension is smaller than D / 2 then we can embed it in the shift on $$\left( [0,1]^D\right) ^{{\mathbb {Z}}^k}$$[0,1]DZk. The value D / 2 here is optimal…
