Tiivistelmä
We give an elementary short proof for a well known theorem of Guibas and Odlyzko stating that thr sets of periods of words are independent of the alphabet size. As a consequence of our constructive proof, we obtain a linear time algorithm which, given a word, computes a binary one with the same periods. We give also a very short proof for the famous Fine Wilf periodicity lemma. (C) 2000 Academic Press.
