... (1) f is separated, (2) ∆f is a closed immersion, (3) ∆f is proper, or (4) ∆f is universally closed. Proof. The statements “f is separated”, “∆f is a closed immersion”, “∆f is universally closed”, and “∆f is proper” refer to the notions defined in Properties of Stacks, Section 3. Choose a scheme V a ...

The goal of the present paper is to study more systematically the hierarchical relationships between “Oka”, “Ako”, their strong analogues, and some other properties (Pi ) introduced in [LR: (2.7)]. These properties (Pi ) (i = 1, 2, 3) are recalled in §2, where (P2 ) and (P3 ) are given more streamli ...

... The intersection of two sets A; B is the collection of all elements which lie in both sets, and is denoted A \ B . Two sets are disjoint if their intersection is . If the intersection is not empty, then we may say that the two sets meet. The union of two sets A; B is the collection of all elements ...

... extra property. That is, a field has inverses under multiplication: if x is in the field and isn’t 0, then there must be an element x−1 = 1/x as well, and it satisfies x · x−1 = 1. In particular, Q, R, and C are fields as well as rings, but Z is not a field. In a field, fractions add and multiply in ...

Algebraic number field

In mathematics, an algebraic number field (or simply number field) F is a finite degree (and hence algebraic) field extension of the field of rational numbers Q. Thus F is a field that contains Q and has finite dimension when considered as a vector space over Q.The study of algebraic number fields, and, more generally, of algebraic extensions of the field of rational numbers, is the central topic of algebraic number theory.
