Paper: Type Theory via Exact Categories (at LICS 1998)

Authors: Lars Birkedal Aurelio Carboni Giuseppe Rosolini Dana S. Scott


Partial equivalence relations (and categories of these) are a standard tool in semantics of type theories and programming languages, since they often provide a cartesian closed category with extended definability. Using the theory of exact categories, we give a category-theoretic explanation of why the construction of a category of partial equivalence relations often produces a cartesian closed category. We show how several familiar examples of categories of partial equivalence relations fit into the general framework
