Square-free partial words
We say that a partial word w over an alphabet A is square-free if every factor xx of w such that x and x are compatible is either of the form ⋄a or a⋄ where ⋄ is a hole and a ∈ A. We prove that there exist uncountably many square-free partial words over a ternary alphabet with an infinite number of holes.
متن کاملThe Number of Positions Starting a Square in Binary Words
We consider the number σ(w) of positions that do not start a square in binary words w. Letting σ(n) denote the maximum of σ(w) for length |w| = n, we show that limσ(n)/n = 15/31. 1 Square-free positions and strong words Every binary word with at least 4 letters contains a square. A.S. Fraenkel and J. Simpson [2, 1] studied the number of distinct squares in binary word; see also Ilie [4], where ...
متن کاملAbelian Square-Free Partial Words
Erdös raised the question whether there exist infinite abelian square-free words over a given alphabet (words in which no two adjacent subwords are permutations of each other). Infinite abelian square-free words have been constructed over alphabets of sizes as small as four. In this paper, we investigate the problem of avoiding abelian squares in partial words (sequences that may contain some h...
متن کاملRestricted square property and infinite partial words
We prove that there exist infinitely many infinite overlap-free binary partial words containing at least one hole. Moreover, we show that these words cannot contain more than one hole and the only hole must occur either in the first or in the second position. We define that a partial word is k-overlap-free if it does not contain a factor of the form xyxyx where the length of x is at least k. We...
متن کاملA Square Root Map on Sturmian Words
We introduce a square root map on Sturmian words and study its properties. Given a Sturmian word of slope α, there exists exactly six minimal squares in its language (a minimal square does not have a square as a proper prefix). A Sturmian word s of slope α can be written as a product of these six minimal squares: s = X2 1X 2 2X 2 3 · · · . The square root of s is defined to be the word √ s = X1...
