We study completely decomposable torsion-free abelian groups of the form GS := nSQpn for sets S . We show that GS has a decidable copy if and only if S is 0 2 and has a computable...

We say a countable model A has a 0-basis if the types realized in A are uniformly computable. We say A has a (d-)decidable copy if there exists a model B = A such that the element...

Much previous study has been done on the degree spectra of prime models of a complete atomic decidable theory. Here we study the analogous questions for homogeneous models. We say...
