On the Structure of Covers of Sofic Shifts

Publikation: Bidrag til tidsskriftTidsskriftartikelfagfællebedømt

  • Rune Johansen
A canonical cover generalizing the left Fischer cover to arbitrary sofic shifts is introduced and used to prove that the left Krieger cover and the past set cover of a sofic shift can be divided into natural layers. These results are used to find the range of a flow-invariant and to investigate the ideal structure of the universal C*-algebra associated to a sofic shift space.
