Geometry of schemes

WebA morphism of schemes is called faithfully flat if it is both surjective and flat. Two basic intuitions regarding flat morphisms are: flatness is a generic property; and; the failure of … WebThis is a flat family. You can see this geometrically, as the fiber over t is a hyperbola when t ≠ 0, and as t approaches 0, the hyperbola gets sharper and sharper and then it "breaks" into two lines when t = 0. Constrast this example with Spec ( k [ x, y, t] / ( t x y − t)) → Spec ( k [ t]). This is not a flat family.
