Realization of aperiodic subshifts and uniform densities in groups
Realization of aperiodic subshifts and uniform densities in groups
A theorem of Gao, Jackson and Seward, originally conjectured to be false by Glasner and Uspenskij, asserts that every countable group admits a 2-coloring. A direct consequence of this result is that every countable group has a strongly aperiodic subshift on the alphabet \{0,1\} . In this article, we use …
