I recently gave a talk about the main points of my MFPS ’12 paper. The title of the talk was Categorical Models for Two Intuitionistic Modal Logics. I first discussed categorical models of intuitionistic S4 based on earlier work by Kobayashi as well as Bierman and de Paiva. I then showed how these models can be extended to become categorical models of an intuitionistic temporal logic with linear time. Since there is a Curry–Howard correspondence between temporal logic and FRP, such models can also serve as models of FRP. The slides of the talk are now online.
