Newly discovered Potentials for Topos Theory from Grothendieck's Handwritten Notes: Functorial Correspondences and Topos Duality: A Reconstruction from Pages (Cote 115)
Abstract
This paper reconstructs and formalizes concepts from Alexander Grothendieck’s handwritten notes
on functorial correspondences and topos duality. It translates his sketches into modern
bicategorical diagrams and ∞-categorical language, bridging logic and geometry.
