WebThe absolute Frobenius morphism is a natural transformation from the identity functor on the category of Fp-schemes to itself. 絶対 フロベニウス写像 は、 Fp-スキーム上の恒等函手からそれ自身への自然な変換である。 In algebraic geometry, a morphism of schemes generalizes a morphism of algebraic varieties just as a scheme generalizes an algebraic variety. It is, by definition, a morphism in the category of schemes. A morphism of algebraic stacks generalizes a morphism of schemes. See more By definition, a morphism of schemes is just a morphism of locally ringed spaces. A scheme, by definition, has open affine charts and thus a morphism of schemes can also be described in terms of such charts (compare the See more Basic ones • Let R be a field or $${\displaystyle \mathbb {Z} .}$$ For each R-algebra A, to specify an element of A, say f in A, is to give a R-algebra … See more By definition, if X, S are schemes (over some base scheme or ring B), then a morphism from S to X (over B) is an S-point of X and one writes: See more Fix a scheme S, called a base scheme. Then a morphism $${\displaystyle p:X\to S}$$ is called a scheme over S or an S-scheme; the idea of … See more Let $${\displaystyle \varphi :B\to A}$$ be a ring homomorphism and let be the induced … See more Finite type Morphisms of finite type are one of the basic tools for constructing families of varieties.
