WitrynaA morphism ϕ: A→ Bof local rings is a complete intersection morphism (resp. a Gorenstein morphism) if B/mABis a complete intersection ring (resp. a Gorenstein ring). (Unlike [EGA] IV 19.3.6, a complete intersection morphism is not necessarily flat. Note also that a S. Brochard Universiteit Leiden, Mathematisch Instituut Witryna2Since the morphism X → S is flat, it is a local complete intersection morphism if and only if every fiber is a local complete intersection morphism (see, e.g., [46], 6.3.23). 3A Dedekind domain in this article has dimension 1, and a Dedekind scheme is the spectrum of a Dedekind domain. WitrynaYour guess is correct. First, the notion of smooth for a morphism is intuitively a property about its fibers. The identity map of a scheme is always smooth. fox pizza in new bethlehem pa
