| contents | Sabok showed that the set of codes for $G_δ$ Ramsey positive subsets of $[ω]^ω$ is $\mathbfΣ^1_2$-complete. We extend this result by providing sufficient conditions for the set of codes for $G_δ$ Ramsey positive subsets of an arbitrary topological Ramsey space to be $\mathbfΣ^1_2$-complete. |
