Witryna1 sie 2024 · A locally Noetherian scheme is a locally Noetherian formal scheme in the canonical way: the formal completion along itself. In other words, the category of locally Noetherian formal schemes contains all locally Noetherian schemes.

Witryna6 cze 2024 · It is a (locally) Noetherian formal scheme. All this serves to state the following theorem, which is sometimes called the fundamental theorem on proper morphisms: Let $ f : X \rightarrow Y $ be a proper morphism of locally Noetherian schemes, $ Y ^ \prime \subset Y $ a closed subscheme, $ X ^ \prime \equiv X \times _ … In algebraic geometry, a noetherian scheme is a scheme that admits a finite covering by open affine subsets $${\displaystyle \operatorname {Spec} A_{i}}$$, $${\displaystyle A_{i}}$$ noetherian rings. More generally, a scheme is locally noetherian if it is covered by spectra of noetherian rings. Thus, a scheme is noetherian if … Zobacz więcej Having a (locally) Noetherian hypothesis for a statement about schemes generally makes a lot of problems more accessible because they sufficiently rigidify many of its properties.
