A third tail invariant measure for the Dyck shift.

Abstract:

The tail relation on the one sided Dyck shift is uniquely ergodic (as shown in this seminar on 10/11/2003), the invariant probability being one of its two equilibrium measures. In addition to its two equilibrium measures, the two sided Dyck shift has another double-tail invariant probability -- shift invariant, non-equilibrium. These are the only three double-tail invariant, ergodic probabilities on the two sided Dyck shift.
