On synchronized coded systems
Wolfgang Krieger
We introduce a class of codes with overlapping code words, that we call SPO-codes. The SPO-codes are related to the Markov codes that were introduced in: G. Keller, J. Combinatoria…

On the subsystems of certain sofic shifts
Wolfgang Krieger
For an aperiodic subshift of finite type and for a subshift with topological entropy less than the topological entropy of , a theorem is proved in Krieger: On the subsys…

On certain labelled directed graphs of symbolic dynamics
Wolfgang Krieger
We consider families of coded systems that contain the Dyck shifts and that are closed under topological conjugacy. We introduce a notion of hyposynchronization of subshifts. We in…
