WebIn general the answer is no. Take k ⊂ K, a finite extension of field (so the morphism Spec ( K) → Spec ( k) is proper). Let X be an affine variety over k. Let now x be a K -point of X that is not defined over k. The corresponding morphism Spec ( K) → X does the job. Share. Cite. Improve this answer. Follow. WebMar 3, 2024 · Theorem 3.2.1 allows us to replace a proper, surjective morphism over the spectrum of a valuation ring by a flat, surjective, proper and finitely presented morphism in our investigation of the derived splinter condition.
