k-Abelian Equivalence and Rationality
Two words u and v are said to be k-abelian equivalent if, for each word x of length at most k, the number of occurrences of x as a factor of u is the same as for v. We study some combinatorial properties of k-abelian equivalence classes. Our starting point is a characterization of k-abelian equivalence by rewriting, so-called k-switching. We show that the set of lexicographically least represen...
متن کاملOn cardinalities of k-abelian equivalence classes
Two words u and v are k-abelian equivalent if for each word x of length at most k, x occurs equally many times as a factor in both u and v. The notion of k-abelian equivalence is an intermediate notion between the abelian equivalence and the equality of words. In this paper, we study the equivalence classes induced by the k-abelian equivalence, mainly focusing on the cardinalities of the classe...
متن کاملVariations of the Morse-Hedlund Theorem for k-Abelian Equivalence
In this paper we investigate local-to-global phenomena for a new family of complexity functions of infinite words indexed by k ∈ N1∪{+∞} where N1 denotes the set of positive integers. Two finite words u and v in A∗ are said to be k-abelian equivalent if for all x ∈ A∗ of length less than or equal to k, the number of occurrences of x in u is equal to the number of occurrences of x in v. This def...
متن کاملOn Generalized Abelian Deformations
We study sun-products on R, i.e. generalized Abelian deformations associated with star-products for general Poisson structures on R. We show that their cochains are given by differential operators. As a consequence, the weak triviality of sun-products is established and we show that strong equivalence classes are quite small. When the Poisson structure is linear (i.e., on the dual of a Lie alge...
متن کاملOn the topological equivalence of some generalized metric spaces
The aim of this paper is to establish the equivalence between the concepts of an $S$-metric space and a cone $S$-metric space using some topological approaches. We introduce a new notion of a $TVS$-cone $S$-metric space using some facts about topological vector spaces. We see that the known results on cone $S$-metric spaces (or $N$-cone metric spaces) can be directly obtained from...
