O que (quem) é Dedekind axiom - definição

THESIS IN MATHEMATICAL LOGIC
Cantor-Dedekind theorem; Cantor-Dedekind Theorem; Cantor-Dedekind axiom

Cantor–Dedekind axiom         
In mathematical logic, the Cantor–Dedekind axiom is the thesis that the real numbers are order-isomorphic to the linear continuum of geometry. In other words, the axiom states that there is a one-to-one correspondence between real numbers and points on a line.
Dedekind cut         
  • irrational]], [[real number]]s.
METHOD OF CONSTRUCTION OF THE REAL NUMBERS
Dedekind cuts; Dedekind section; Completion (order theory); Dedekind's Axiom; Dedekind Cut
In mathematics, Dedekind cuts, named after German mathematician Richard Dedekind but previously considered by Joseph Bertrand, are а method of construction of the real numbers from the rational numbers. A Dedekind cut is a partition of the rational numbers into two sets A and B, such that all elements of A are less than all elements of B, and A contains no greatest element.
Axiom schema         
A FORMULA IN THE METALANGUAGE OF AN AXIOMATIC SYSTEM IN WHICH ONE OR MORE SCHEMATIC VARIABLES APPEAR
Axiom scheme; Axiom schemata; Axiom-scheme; Finite axiomatization
In mathematical logic, an axiom schema (plural: axiom schemata or axiom schemas) generalizes the notion of axiom.

Cantor–Dedekind axiom

In mathematical logic, the Cantor–Dedekind axiom is the thesis that the real numbers are order-isomorphic to the linear continuum of geometry. In other words, the axiom states that there is a one-to-one correspondence between real numbers and points on a line.

This axiom is the cornerstone of analytic geometry. The Cartesian coordinate system developed by René Descartes implicitly assumes this axiom by blending the distinct concepts of real number system with the geometric line or plane into a conceptual metaphor. This is sometimes referred to as the real number line blend.

A consequence of this axiom is that Alfred Tarski's proof of the decidability of first-order theories of the real numbers could be seen as an algorithm to solve any first-order problem in Euclidean geometry.

However, with the development of axiom systems for synthetic geometry that filled in the axioms that Euclid implicitly assumed, and the development of modern notions of the real numbers, both the Euclidean line and the Reals are complete Archimedean fields, thus canonically isomorphic, and the Cantor–Dedekind "axiom" is actually a theorem.
