Occurrences of palindromes in characteristic Sturmian words [PDF]

open access: yes, 2006
This paper is concerned with palindromes occurring in characteristic Sturmian words cα of slope α, where α∈(0,1) is an irrational. As cα is a uniformly recurrent infinite word, any (palindromic) factor of cα occurs infinitely many times in cα with ...

On the Lie complexity of Sturmian words

open access: yesTheoretical Computer Science, 2022
Bell and Shallit recently introduced the Lie complexity of an infinite word $s$ as the function counting for each length the number of conjugacy classes of words whose elements are all factors of $s$. They proved, using algebraic techniques, that the Lie complexity is bounded above by the first difference of the factor complexity plus one; hence, it is

Quasiperiodic and Lyndon episturmian words [PDF]

open access: yes, 2008
Recently the second two authors characterized quasiperiodic Sturmian words, proving that a Sturmian word is non-quasiperiodic if and only if, it is an infinite Lyndon word.

Conjugates of characteristic Sturmian words generated by morphisms [PDF]

open access: yes, 2004
This article is concerned with characteristic Sturmian words of slope α and 1-α (denoted by cα and c1-α resp.), where α∈(0,1) is an irrational number such that α=[0;1+d1,d2,..., dn] with dn≥d1≥1.

Powers in a class of A-strict standard episturmian words [PDF]

open access: yes, 2007
This paper concerns a specific class of strict standard episturmian words whose directive words resemble those of characteristic Sturmian words. In particular, we explicitly determine all integer powers occurring in such infinite words, extending recent ...

Abelian Repetitions in Sturmian Words [PDF]

open access: yes, 2013
We investigate abelian repetitions in Sturmian words. We exploit a bijection between factors of Sturmian words and subintervals of the unitary segment that allows us to study the periods of abelian repetitions by using classical results of elementary Number Theory.

Episturmian words: a survey [PDF]

open access: yes, 2007
In this paper, we survey the rich theory of infinite episturmian words which generalize to any finite alphabet, in a rather resembling way, the well-known family of Sturmian words on two letters.

Return words in Sturmian and episturmian words [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2000
Summary: Considering each occurrence of a word \(w\) in a recurrent infinite word, we define the set of return words of \(w\) to be the set of all distinct words beginning with an occurrence of \(w\) and ending exactly just before the next occurrence of \(w\) in the infinite word. We give a simpler proof of the recent result (of the second author) that,
