Allahbakhshi, Mahsa; Hong, Soonjo; Jung, Utun (Taylor & Francis, 2015)We define class-closing factor codes from shifts of finite type and show that they are continuing if their domains are irreducible and their images are of finite type. We establish several relations between class-closing ...

Allahbakhshi, Mahsa; Hong, Soonjo; Jung, Uijin (Cambridge University Press, 2015)Given a factor code pi from a shift of finite type X onto a sofic shift Y, the class degree of pi is defined to be the minimal number of transition classes over the points of Y. In this paper, we investigate the structure ...
