Abstract:
We construct a decidable prime model in which the degree of a set of complete formulas is equal to $\mathbf{0}'$, infinitely many tuples of elements comply with every complete formula, and the decidable categoricity spectrum coincides with the set of all $PA$-degrees.
Keywords:
computable model, decidable model, computable categoricity, autostability relative to strong constructivizations, degree of decidable categoricity, decidable categoricity spectrum, $PA$-degree.
