Realizing realizability results with classical constructions
arXiv:1905.08202 · doi:10.1017/bsl.2019.59
Abstract
J.L. Krivine developed a new method based on realizability to construct models of set theory where the axiom of choice fails. We attempt to recreate his results in classical settings, i.e. symmetric extensions. We also provide a new condition for preserving well-ordered, and other particular type of choice, in the general settings of symmetric extensions.
