Journal ArticleDOI
Rich words in the block reversal of a word
TL;DR: The authors showed that for a binary word w, richness of all elements of BR(w) depends on l(w), the length of the run sequence of w. They also provided the structure of such words.
Book ChapterDOI
Binary images, M-vectors, and ambiguity
TL;DR: This work introduces the notion of M-vector of a binary word which allows us to have a linear notation in the form of a unique vector representation of the Parikh matrix of the binary word and extends this notion to a binary image treating it as a binary array over a two-symbol alphabet.
Morphisms and Weak-Ratio Property.
TL;DR: General morphisms on words are considered and various properties related to subwords, in the context of a weak-ratio property considered in [12], are obtained.
Journal ArticleDOI
Counting (Watson-Crick) palindromes in Watson-Crick conjugates
TL;DR: In this article , a generalization of conjugates of a word that incorporate the notion of WK-involution is studied, called θ-conjugates or WKconjugate.
BookDOI
Theta palindromes in theta conjugates
TL;DR: In this article, the distribution of palindromes and WK-palindrome conjugates of a word has been studied in terms of the number of elements in the conjugate set.
