Modeling Univalence in Inverse Diagrams

Homotopy Type Theory

I have just posted the following preprint, which presents new set-theoretic models of univalence in categories of simplicial diagrams over inverse categories (or, more generally, diagrams over inverse categories starting from any existing model of univalence).

For completeness, I also included a sketch of how to use a universe object to deal with coherence in the categorical interpretation of type theory, and of the meaning of various basic notions in homotopy type theory under categorical semantics in homotopy theory.
