Normalization of integral scheme
Webfor the spectrum of an integral domain. An integral scheme is also irreducible: otherwise, it would contain two disjoint open a ne subschemes U 1;U 2, and then U 1 [U 2 would be a ne with coordinate ring O(U 1) O (U 2) which is not an integral domain. Conversely, any scheme Xwhich is reduced and irreducible is integral: every open a ne WebTools. In mathematics, the Noether normalization lemma is a result of commutative algebra, introduced by Emmy Noether in 1926. [1] It states that for any field k, and any finitely generated commutative k -algebra A, there exist algebraically independent elements y1, y2, ..., yd in A such that A is a finitely generated module over the polynomial ...

Web22 de jan. de 2010 · In general, normality implies regular in codimension 1 (to be precise, normality is equivalent to ( R 1) and ( S 2) by Serre). So for curves, it implies regularity. For dimension 2, look at Spec ( k [ x, y, z] / ( x 2 + y 2 + z 3) ). It is normal, but not regular. WebLemma 29.54.5. Let be a scheme such that every quasi-compact open has finitely many irreducible components. The normalization is a disjoint union of integral normal schemes. The morphism is integral, surjective, and induces a bijection on irreducible components.

(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.
