Morphisms generating antipalindromic words
Petr Ambrož, Zuzana Masáková, Edita Pelantová
We introduce two classes of morphisms over the alphabet whose fixed points contain infinitely many antipalindromic factors. An antipalindrome is a finite word invariant…
Numbers with integer expansion in the numeration system with negative base
P. Ambrož, D. Dombek, Z. Masákova +1
In this paper, we study representations of real numbers in the positional numeration system with negative basis, as introduced by Ito and Sadahiro. We focus on the set of…
On the number of factors in codings of three interval exchange
Petr Ambrož, Anna Frid, Zuzana Masáková +1
We consider exchange of three intervals with permutation . The aim of this paper is to count the cardinality of the set $3\iet(N)$ of all words of length which appear…
Morphisms fixing words associated with exchange of three intervals
Petr Ambrož, Zuzana Masáková, Edita Pelantová
We consider words coding exchange of three intervals with permutation (3,2,1), here called 3iet words. Recently, a characterization of substitution invariant 3iet words was provide…
A note on 3iet preserving morphisms
P. Ambroz, E. Pelantova
An infinite word, which is aperiodic and codes the orbit of a transformation of the exchange of three intervals is called 3iet word. Such a word is thus a natural generalization of…
Matrices of 3iet preserving morphisms
P. Ambroz, Z. Masáková, E. Pelantová
We study matrices of morphisms preserving the family of words coding 3-interval exchange transformations. It is well known that matrices of morphisms preserving sturmian words (i.e…
