Abstract
A word w is primitive if it is not a proper power of another word, and w is unbordered if it has no prefix that is also a suffix of w. We study the number of primitive and unbordered words w with a fixed weight, that is, words for which the Parikh vector of w is a fixed vector. Moreover, we estimate the number of words that have a unique border. (c) 2005 Elsevier B.V All rights reserved.
