Palindromic length and reduction of powers

aperiodic infinite word x, the palindromic length of its factors is not bounded. Let x be an infinite aperiodic word with a bounded palindromic length and containing infinitely many occurrences of the fif...

Note on powers in three interval exchange transformations

We study repetitions in infinite words coding exchange of three intervals with permutation (3,2,1), called 3iet words. The language of such words is determined by two parameters $varepsilon,ell$. We show that finit...

Relation between powers of factors and the recurrence function characterizing Sturmian words

In this paper we use the relation of the index of an infinite aperiodic word and its recurrence function to give another characterization of Sturmian words. As a byproduct, we give a new proof of theorem describing the inde...

Critical Exponent of Infinite Words Coding Beta-integers Associated with Non-simple Parry Numbers

In this paper, we study the critical exponent of infinite words u coding beta- integers for beta being a non-simple Parry number. In other words, we investigate the maximal consecutive repetitions of factors that occur in t...

Construction of a Bi-infinite Power Free Word with a Given Factor and a Non-recurrent Letter

Let L(k,α) denote the set of all bi-infinite α-power free words over an alphabet with k letters, where α is a positive rational number and k is a positive integer. We prove that if α>=5, k>=3, velementL(k,α), and w is a fin...

Return Words and Recurrence Function of a Class of Infinite Words

Many combinatorial and arithmetical properties have been studied for infinite words associated with beta-integers. Here, new results describing return words and recurrence function for a special class of such words...

Infinite Words with Well Distributed Occurrences

In this paper we study how certain families of aperiodic infinite words can be used to produce aperiodic pseudorandom number generators (PRNGs) with good statistical behavior. We introduce the well distributed occurrences (WELLDOC) ...

All About Infinite Words Associated with Quadratic Non-simple Parry Numbers

Study of factor complexity, palindromic complexity, and return words of infinite aperiodic words is an interesting combinatorial problem. Moreover, investigation of infinite words coding beta-integers, whi...
