3-Abelian Cubes Are Avoidable on Binary Alphabets

چکیده
A k-abelian cube is a word uvw, where u, v, w have the same factors of length at most k with the same multiplicities. Previously it has been known that k-abelian cubes are avoidable over a binary alphabet for k ≥ 5. Here it is proved that this holds for k ≥ 3.

On some generalizations of abelian power avoidability
We prove that 2-abelian-cubes are avoidable over a binary alphabet and that 3-abelian-squares are avoidable over a ternary alphabet, answering positively to two questions of Karhumäki et al.. We also show the existence of infinite additive-cube-free words on several ternary alphabets. To achieve this, we give sufficient conditions for a morphism to be k-abelian-n-power-free (resp. additive-n-po...
متن کاملAvoidability of long k-abelian repetitions
We study the avoidability of long k-abelian-squares and k-abeliancubes on binary and ternary alphabets. For k = 1, these are Mäkelä’s questions. We show that one cannot avoid abelian-cubes of abelian period at least 2 in infinite binary words, and therefore answering negatively one question from Mäkelä. Then we show that one can avoid 3-abelian-squares of period at least 3 in infinite binary wo...
متن کاملAvoiding 2-binomial squares and cubes
Two finite words u, v are 2-binomially equivalent if, for all words x of length at most 2, the number of occurrences of x as a (scattered) subword of u is equal to the number of occurrences of x in v. This notion is a refinement of the usual abelian equivalence. A 2-binomial square is a word uv where u and v are 2-binomially equivalent. In this paper, considering pure morphic words, we prove th...
متن کاملEvery Binary Pattern of Length Greater Than 14 Is Abelian-2-Avoidable
We show that every binary pattern of length greater than 14 is abelian-2-avoidable. The best known upper bound on the length of abelian-2-unavoidable binary pattern was 118, and the best known lower bound is 7. We designed an algorithm to decide, under some reasonable assumptions, if a morphic word avoids a pattern in the abelian sense. This algorithm is then used to show that some binary patte...
متن کاملAvoiding two consecutive blocks of same size and same sum over $\mathbb{Z}^2$
We exhibit an algorithm to decide if the fixed-points of a morphism avoid (long) abelian repetitions and we use it to show that long abelian squares are avoidable over the ternary alphabet. This gives a partial answer to one of Mäkelä's questions. Our algorithm can also decide if a morphism avoids additive repetitions or k-abelian repetitions and we use it to show that long 2-abelian square are...
