Any reduced scheme X has a unique normalization: a normal scheme Y with an integral birational morphism Y → X. (For X a variety over a field, the morphism Y → X is finite, which is stronger than "integral". ) The normalization of a scheme of dimension 1 is regular, and the normalization of a scheme of dimension 2 has only isolated singularities. Normalization is not usually used for resolution of singularities for schemes of higher dimension. WebZariski topology of schemes.

WebIn order to determine the normalization constant ψ0, we simply substitute Equation ( [e3.5]) into Equation ( [e3.4]) to obtain ψ0 2∫∞ − ∞e − ( x − x0)2 / ( 2σ2) dx = 1. Changing the variable of integration to y = (x − x0) / (√2σ), we get ψ0 2√2σ∫∞ − ∞e − y2dy = 1. However , ∫∞ − ∞e − y2dy = √π, which implies that ψ0 2 = 1 (2πσ2)1 / 2.

WebLet π: X → Y be an integral morphism of schemes such that X is integral and normal and such that π induces on function fields the extension K ( Y) ⊂ L = K ( X). Then X is the normalization of Y in L. In fact this follows essentially from the definition of "normalization" and the fact that integral ring homomorphisms are stable under localization. WebLet X be a variety (a separated integral scheme) with function field K = k ( X), maybe assumed normal. Let L be a finite separable extension of K. From this data, we can construct a variety Y with k ( Y) = L together with a finite surjective map π: Y → X, called the normalization of X in L.
