Condensed Sets and the Solovay Model – teaching an old dog new tricks

28.05.2026 11:30 - 13:00

D. Basak (U Paris-Cité, FR)

The talk will be an overview of the recent joint project with Nathaniel Bannister (Carnegie-Mellon University) connecting the Condensed Sets of Clausen-Scholze with the Solovay model \(V(R)\) (obtained by collapsing an inaccessible) via a geometric morphism of topoi. The goal will be to make precise what this morphism is, and to talk about a new choice principle for the Solovay model that was discovered by accident in the course of this research.
