Implicative models of intuitionistic set theory

Abstract: In this paper we will show that using implicative algebras one can produce models of intuitionistic set theory generalizing both realizability and Heyting-valued models. This has as consequence that if one assumes the inaccessible cardinal axiom, then every topos which is obtained from a Set-based tripos as the result of the tripos-to-topos construction hosts a model of intuitionistic set theory.
