Infinite ternary square-free words concatenated from permutations of a single word

چکیده
We answer a question of Harju: An infinite square-free ternary word with an n-stem factorization exists for any n ≥ 13. We show that there are uniform ternary morphisms of length k for every k ≥ 23. This resolves almost completely a problem of the author and Rampersad.

The minimal density of a letter in an infinite ternary square - free word is 0 . 2746
We study the minimal density of letters in infinite square-free words. First, we give some definitions of minimal density in infinite words and prove their equivalence. Further, we propose a method that allows to strongly reduce an exhaustive search for obtaining lower bounds for minimal density. Next, we develop a technique for constructing square-free morphisms with extremely small density fo...
متن کاملA Ternary Square-free Sequence Avoiding Factors Equivalent to $abcacba$
We solve a problem of Petrova, finalizing the classification of letter patterns avoidable by ternary square-free words; we show that there is a ternary square-free word avoiding letter pattern xyzxzyx. In fact, we • characterize all the (two-way) infinite ternary square-free words avoiding letter pattern xyzxzyx • characterize the lexicographically least (one-way) infinite ternary square-free w...
متن کاملSubword complexity and power avoidance
We begin a systematic study of the relations between subword complexity of infinite words and their power avoidance. Among other things, we show that – the Thue-Morse word has the minimum possible subword complexity over all overlapfree binary words and all (73)-power-free binary words, but not over all ( 7 3) +-power-free binary words; – the twisted Thue-Morse word has the maximum possible sub...
متن کاملSquare-free shuffles of words
Let u v denote the set of all shuffles of the words u and v . It is shown that for each integer n ≥ 3 there exists a square-free ternary word u of length n such that u u contains a square-free word. This property is then shown to also hold for infinite words, i.e., there exists an infinite square-free word u on three letters such that u can be shuffled with itself to produce an infinite square-...
متن کاملUnequal letter frequencies in ternary square-free words
We consider the set S of triples (x, y, z) corresponding to the frequency of each alphabet letter in some infinite ternary square-free word (so x + y+ z = 1). We conjecture that this set is convex. We obtain bounds on S by with a generalization of our method to bound the extremal frequency of one letter. This method uses weights on the alphabet letters. Finally, we obtain positive results, that...
