Class-closing factor codes and constant-class-to-one factor codes from shifts of finite type
Mahsa Allahbakhshi, Soonjo Hong, Uijin Jung
We define class-closing factor codes from shifts of finite type and show that they are continuing if their images are of finite type. We establish several relations between class-c…

The multiplicative inequality for class degrees via relative transition classes
Soonjo Hong
Generalizing the notion of the degree of a finite-to-one factor code from a shift of finite type, the class degree of a possibly infinite-to-one factor extends many important prope…
