Abstract
In a recent paper with L. Q. Zamboni the authors introduced the class of ϑ-episturmian words, where ϑ is an involutory antimorphism of the free monoid A *. In this paper, we introduce and study ϑ-characteristic morphisms, that is, morphisms which map standard episturmian words into standard ϑ-episturmian words. They are a natural extension of standard episturmian morphisms. The main result of the paper is a characterization of these morphisms when they are injective.
