enriched hom-functor

The concept of *enriched hom-functor* is the generalization of that of hom-functors from category theory to enriched category theory.

**(enriched hom-functor)**

For $\mathcal{V}$ a closed symmetric monoidal category with all limits and colimits, let $\mathcal{C}$, be a $\mathcal{V}$-enriched categories. Then its *$\mathcal{V}$-enriched hom-functor* is the $\mathcal{V}$-enriched functor

$\mathcal{C}(-,-)
\;\colon\;
\mathcal{C}^{op} \times \mathcal{C}
\longrightarrow
\mathcal{V}$

from the enriched product category of $\mathcal{C}$ with its enriched opposite category to $\mathcal{V}$, canonically regarded as enriched over itself, which sends pairs of objects to the corresponding hom-object in $\mathcal{C}$

$c_1,c_2 \mapsto \mathcal{C}(c_1,c_2)$

and wich omn hom-objects of $\mathcal{C}^{op} \times \mathcal{C}$ is given by the evident pre- and post-composition operation.
