A note on near-optimal coloring of shift hypergraphs

ABSTRACT As shown in the original work on the Lovász Local Lemma due to Erdős & Lovász (Infinite and Finite Sets, 1975), a basic application of the Local Lemma answers an infinitary coloring question of Strauss, showing that given any integer set S, the integers may be k‐colored so that S and all its translates meet every color. The quantitative bounds here were improved by Alon, Kriz & Nesetril (Studia Scientiarum Mathematicarum Hungarica, 1995). We obtain an asymptotically optimal bound in this note, using the technique of iteratively applying the Lovász Local Lemma in order to prune dependencies. © 2014 Wiley Periodicals, Inc.
