[2103.11748] Forcing the $Π^1_n$-Uniformization Property Skip to main content Search Submit Donate Log in Mathematics > Logic arXiv:2103.11748 (math) [Submitted on 22 Mar 2021 ( v1 ), last revised 25 Aug 2026 (this version, v5)] Title: Forcing the $Π^1_n$-Uniformization Property Authors: Stefan Hoffelner View PDF HTML (experimental) Abstract: We generically construct a model in which the ${\Pi^1_3}$-uniformization property is true, thus lowering the best known consistency strength from the existence of $M_1^{\#}$ to just $\mathsf{ZFC}$. The forcing construction can be adapted to work over canonical inner models with Woodin cardinals, which yields, for the first time, universes where the $\Pi^1_{2n}$-uniformization property holds for $n >1$, thus producing models which contradict the natural $\mathsf{PD}$-induced pattern.
