Abstract:
A full isomorphism-closed subcategory $\mathcal {A}$ of a complete well-powered and co-well-powered category $\mathcal {C}$ is both co-well-powered (in its own right) and reflective in $\mathcal {C}$ if and only if (a) $\mathcal {A}$ is closed in $\mathcal {C}$ under the formation of ($U$-small-indexed) limits, and (b) the epi-reflective hull $\mathcal {B}$ of $\mathcal {A}$ in $\mathcal {C}$ is co-well-powered.References
