Compactness of maximal eventually different families

Logic 2022-10-11 v2

Abstract

We show that there is an effectively closed maximal eventually different family of functions in spaces of the form nF(n)\prod_n F(n) for F ⁣:NN{N}F\colon \mathbb{N} \to \mathbb{N}\cup\{\mathbb{N}\} and give an exact criterion for when there exists an effectively compact such family.
