representables as collection of generators
Proposition
Let \(\mathcal{C}\) be a locally small infinity category, \(\mathcal{P}(\mathcal{C})\) be the infinity presheaf category.
Then the colleciton of representable functors is a collection of generators in \(\mathcal{P}(\mathcal{C})\)
Proof
follows from the contravariant infinity yoneda lemma, where
- \(\mathrm{map}_{\mathcal{P}(\mathcal{C})(\mathrm{map}_{\mathcal{C}}(-,c), \mathcal{F}) \cong \mathcal{F}(C)\)
- and higher morphisms follow from the naturality (todo)
