Some papers:
- The Yoneda embedding is natural, Maxime Razi (2022).
- Definability, interpretations and étale fundamental groups, Romin Abdolahzadi and Boris Zilber (2020).
- Codensity and the ultrafilter monad, Tom Leinster (2013).
- Gödel diffeomorphisms, Matthew Foreman (2020). A self-diffeomorphism of the torus need not be “measure-theoretically isomorphic” to its inverse (defined on page 4). This paper explains how certain statements (e.g. the Riemann hyothesis, Goldbach’s conjecture) are equivalent to certain self-diffeomorphisms of the torus being isomorphic to their inverses(!)
