Abstract
We present a streamlined proof of a result essentially present in previous work of the author, namely that for every set of zero Banach density and finite set , there exists a minimal zero-entropy subshift so that for every sequence , there is with for all . Informally, minimal deterministic sequences can achieve completely arbitrary behavior upon restriction to a set of zero Banach density. As a corollary, this provides counterexamples to the Polynomial Sarnak Conjecture which are significantly more general than some recently provided in word of Kanigowski, Lema\'{n}czyk, and Radziwi\l\l and of Lian and Shi, and shows that no similar result can hold under only the assumptions of minimality and zero entropy.
