Let (M, X) satisfies ACA(0) be such that P-X, the collection of all unbounded sets in X, admits a definable complete ultrafilter and let T be it theory extending first order arithmetic coded in C such that M thinks T is consistent. We prove that there is an end-extension N satisfies T of M such that the subsets of M coded in N are precisely those in X. As a special case we get that any Scott set with a definable ultrafilter coding it consistent theory T extending first order arithmetic is the standard system of it recursively saturated model of T. |
