WebState space A(ε) is spanned by B-linear combinations of 1-manifolds M with ∂M ∼=ε, modulo relations: two linear combinations are equal if for any way to close them up and … Finite type Morphisms of finite type are one of the basic tools for constructing families of varieties. A morphism $${\displaystyle f:X\to S}$$ is of finite type if there exists a cover $${\displaystyle \operatorname {Spec} (A_{i})\to S}$$ such that the fibers $${\displaystyle X\times _{S}\operatorname {Spec} (A_{i})}$$ can … See more 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. See more Let $${\displaystyle \varphi :B\to A}$$ be a ring homomorphism and let be the induced map. Then • 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: $${\displaystyle X(S)=\{f\mid f:S\to X{\text{ over }}B\}}$$ for the set of all S … 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 … 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 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 homomorphism $${\displaystyle R[t]\to A}$$ such that • Similarly, for any S … See more A rational map of schemes is defined in the same way for varieties. Thus, a rational map from a reduced scheme X to a separated scheme Y is an equivalence class of a pair See more
