Σ _1^1 in Every Real in a Σ _1^1 Class of Reals Is Σ _1^1

We …rst prove a theorem about reals (subsets of N) and classes of reals: If a real X is 1 in every member G of a nonempty 1 1 class K of reals then X is itself 1. We also explore the relationship between this theorem, various basis results in hyperarithmetic theory and omitting types theorems in !-logic. We then prove the analog of our …rst theorem for classes of reals: If a class A of reals is...
