| May 1, 2022 at 14:48 | comment | added | PrimeRibeyeDeal | Is the last remark true? On the nlab page for dense functors it is stated that density is not transitive, and an example is given using the simplex subcategory of Cat. | |
| Oct 21, 2016 at 14:05 | comment | added | Martin Brandenburg | @Arrow: This is also true by the Yoneda Lemma, but density of $C \subseteq C$ is also the Yoneda Lemma: It says that $\hom(X,Y) \cong \hom(\hom(-,X),\hom(-,Y))$. | |
| Jun 29, 2016 at 17:57 | comment | added | Arrow | Shouldn't it be "$\mathsf C$ is dense in $\widehat{\mathsf C}$"? | |
