In a recent paper with L. Q. Zamboni, the authors introduced the class of
*$\vartheta$-episturmian* words. An infinite word over $A$ is standard
$\vartheta$-episturmian, where $\vartheta$ is an involutory antimorphism of
$A^{\*}$, if its set of …
In this paper we study a class of infinite words on a finite alphabet
$A$ whose factors are closed under the image of an involutory
antimorphism $\theta$ of the free monoid $A^\*$.
We show that given a
recurrent infinite word $\omega \in …
In a recent paper with L. Q. Zamboni the authors introduced the class of
*$\vartheta$-episturmian* words, where $\vartheta$ is an involutory
antimorphism of the free monoid $A^{*}$. In this paper, we introduce and study …
In this paper we study some classes of infinite words generalizing episturmian
words, and analyse the relations occurring among such classes. In each case, the
reversal operator $R$ is replaced by an arbitrary involutory antimorphism
$\vartheta$ …
We study some classes of infinite words that generalize standard episturmian
words, defined by replacing the reversal operator with an arbitrary involutory
antimorphism $\vartheta$ of $A^{\*}$. An analysis of the relations occurring among
such …
