Improved Bounds on the Length of Maximal Abelian Square-free Words
A word is abelian square-free if it does not contain two adjacent subwords which are permutations of each other. Over an alphabet Σk on k letters, an abelian squarefree word is maximal if it cannot be extended to the left or right by letters from Σk and remain abelian square-free. Michael Korn proved that the length `(k) of a shortest maximal abelian square-free word satisfies 4k − 7 ≤ `(k) ≤ 6...
متن کاملImproved bounds on the number of ternary square-free words
Improved upper and lower bounds on the number of squarefree ternary words are obtained. The upper bound is based on the enumeration of square-free ternary words up to length 110. The lower bound is derived by constructing generalised Brinkhuis triples. The problem of finding such triples can essentially be reduced to a combinatorial problem, which can efficiently be treated by computer. In part...
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 کاملAbelian-square-rich words
An abelian square is the concatenation of two words that are anagrams of one another. A word of length n can contain at most Θ(n) distinct factors, and there exist words of length n containing Θ(n) distinct abelian-square factors, that is, distinct factors that are abelian squares. This motivates us to study infinite words such that the number of distinct abelian-square factors of length n grow...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
