Solovay's inaccessible over a weak set theory without choice

Logic 2023-09-12 v2

Abstract

We study the consistency strength of Lebesgue measurability for Σ31\Sigma^1_3 sets over Zermelo set theory (ZZ) in a completely choiceless context. We establish a result analogous to the Solovay-Shelah theorem.
