Coherent topos

In mathematics, a coherent topos is a topos generated by a collection of quasi-compact quasi-separated objects closed under finite products.^[1]

Deligne's completeness theorem says a coherent topos has enough points.^[2] William Lawvere noticed that Deligne's theorem is a variant of the Gödel completeness theorem for first-order logic.^[3]
