In this paper we solve some open problems related to (pseudo)palindrome closure
operators and to the infinite words generated by their iteration, that is,
standard episturmian and pseudostandard words. We show that if
$\vartheta$ is an …
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 …
We consider involutory antimorphisms $\vartheta$ of a free monoid $A^{\*}$ and
their fixed points, called $\vartheta$-palindromes or pseudopalindromes. A
$\vartheta$-palindrome reduces to a usual palindrome when $\vartheta$ is the
reversal …
