Morphism of schemes
WebDefinition. A morphism of schemes : is called a Nisnevich morphism if it is an étale morphism such that for every (possibly non-closed) point x ∈ X, there exists a point y ∈ Y in the fiber f −1 (x) such that the induced map of residue fields k(x) → k(y) is an isomorphism.Equivalently, f must be flat, unramified, locally of finite presentation, and for … 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。
