Resumen de Kripke-Joyal forcing for type theory and uniform fibrations

Steve Awodey, Nicola Gambino, Sina Hazratpour

• We introduce a new method for precisely relating algebraic structures in a presheaf category and judgements of its internal type theory. The method provides a systematic way to organise complex diagrammatic reasoning and generalises the well-known Kripke-Joyal forcing for logic. As an application, we prove several properties of algebraic weak factorisation systems considered in Homotopy Type Theory
