Enriched Category Theory (Topic)

Enriched Category Theory

This is a new, contributed topic on enrichments of category theory, including a weak Yoneda lemma, functor categories, 2-categories and representable V-functors.

Monoidal Categories

$2-category$ VCAT for a monoidal V category $2-functors$, such as $F: VCAT \to CAT$

Tensor products and duality Closed and bi-closed bimonoidal categories

Representable V functors Extraordinary V naturality and the V naturality of the canonical maps

The Weak Yoneda Lemma for VCAT

Adjunctions and equivalences in VCAT

$2-Functor$ categories

The functor category $[A,B]$ for small A

The (strong) Yoneda lemma for VCAT and the Yoneda embedding

The free V category on a Set category

Universe enlargement $V \to enV$ : consider $[A,B]$ as an enV category

The isomorphism $[A \times [B, C]] \cong [A,[B,C]]$

Indexed limits and colimits

Indexing types; limits and colimits; Yoneda isomorphisms

Preservation of limits and colimits

Limits in functor categories: double limits and iterated limits

The connection with classical conical limits when $V = Set$

Full subcategories and limits: the closure of a full subcategory

Strongly generating functors

Tensor and Cotensor Products

Kan extensions

The definition of Kan extensions: their expressibility by limits and colimits

Iterated Kan extensions. Kan adjoints

Filtered categories when $V = Set$

General Representability and Adjoint Functor theorems

Representability and adjoint-functor theorems when $V = Set$

Functor categories, small Projective Limits and Morita Equivalence

more to come
