ENRICHED INDEXED CATEGORIES
"... Abstract. We develop a theory of categories which are simultaneously (1) indexed over a base category S with finite products, and (2) enriched over an Sindexed monoidal category V. This includes classical enriched categories, indexed and fibered categories, and internal categories as special cases. ..."

Abstract. We develop a theory of categories which are simultaneously (1) indexed over a base category S with finite products, and (2) enriched over an Sindexed monoidal category V. This includes classical enriched categories, indexed and fibered categories, and internal categories as special cases. We then describe the appropriate notion of “limit ” for such enriched indexed categories, and show that they admit “free cocompletions” constructed as usual with a Yoneda embedding.
Logical Construction of Final Coalgebras
, 2003
"... We prove that every finitary polynomial endofunctor of a category C has a final coalgebra, provided that C is locally Cartesian closed, it has finite coproducts and is an extensive category, it has a natural number object. ..."
