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]
