A note of ins-primitive words

open access: yesInternational Journal of Computer Mathematics, 2004
The aim of this article is to investigate the properties of primitive words with respect to insertion operation, called ins-primitive words. This includes the investigation of properties concerning primitive words (with respect to catenation operation) in order to show our result concerning the self-insertion of a word. We also show that the set of all

Count of primitive words

Applied Mathematics, 2001
The author counts the primitive words of given length on a finite alphabet, as well as the ``exchangeable'' primitive words on a finite alphabet (a word is noexchangeable primitive if the word obtained by applying any permutation to the letters is still primitive). The first result is well known and can be found in any book on combinatorics on words (a

Counting bordered and primitive words with a fixed weight

open access: yesTheoretical Computer Science, 2005
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
