We present the internal type theory of a Heyting pretopos with a natural numbers object. The resulting theory is based on dependent types and proof-terms. We prove that there is a sort of equivalence between such type theories and the category of Heyting pretoposes. By using the type theory we also build the free Heyting pretopos generated by a category.

Abstract

We present the internal type theory of a Heyting pretopos with a natural numbers object. The resulting theory is based on dependent types and proof-terms. We prove that there is a sort of equivalence between such type theories and the category of Heyting pretoposes. By using the type theory we also build the free Heyting pretopos generated by a category.
