On a Generalization of Equilogical Spaces

  • Fabio PasqualiEmail author


We use the theory of triposes to prove that every (non-degenerate) locale H is the set of truth values of a complete and co-complete quasi-topos into which the category of topological spaces embeds and the topos of sheaves over H reflectively embeds.
