WebDefinition 1 (Mumford divisors). Let f: X → S be a flat morphism with S2 fibers of pure dimension n . A subscheme D ⊂ X is a relative Mumford divisor or a generically flat family of Mumford divisors over S if there is an open subset U ⊂ X such that codimXs(Xs ∖U) ≥ 2 for every s ∈ S, D U is a relative Cartier divisor, D is the closure of D U and WebGeneric flatness. Basically this says that a finite type algebra over a domain becomes flat after inverting a single element of the domain. There are several versions of this result (in …

WebFeb 26, 2015 · Theorem 1.1. be a projective flat family of irreducible varieties X_b, b \in B. Assume that all fibers X_b (b a closed point of B) are birational to each other. Let X_0 be a projective model of the fibers, contained in some \mathbb {P}^s. Then the family is birationally isotrivial, by which we mean that, equivalently, WebThe bZ4X is distinctive and overall generically attractive. The front end, and in particular the crisp leading edge of the hoodline, and the thin, sharply styled headlights, is an exception to that. WebJan 1, 2006 · A coherent sheaf is flat if and only if it is locally free. We mention flatness, rather then local freeness, since we will relate it with flatness of projective morphism. Rossi introduces this notion of blowing up at coherent module, with the universal flat- tening property, within the complex analytic context. mexican food sprague spokane valley
