Some Decision Results on Nonrepetitive Words

Part of the NATO ASI Series book series (volume 12)


The paper addresses some generalizations of the Thue Problem such as: given a word u, does there exist an infinite nonrepetitive overlap free (or square free) word having u as a prefix? A solution to this as well as to related problems is given for the case of overlap free words on a binary alphabet.
