### axiom of choice (countable and uncountable, plural axioms of choice) ( set theory ) One of the axioms of set theory , equivalent to the statement that an arbitrary direct product of non-empty sets is non-empty; any version of said axiom, for example specifying the cardinality of the number of sets from which choices are made.

Posted by Alexandre Borovik  The axiom of choice is an important and controversial axiom in set theory and mathematical logic. It was formulated by Zermelo in 1904 and was later shown to   Download Axiom of Choice (Lecture Notes in Mathematics Vol. 1876)# Ebook Free. Smay1931. The biggest problem with the Axiom of Choice is that it yields the existence of some objects that are not de nable or cannot be explicitly constructed. This treatise shows paradigmatically that: Disasters happen without AC: Many fundamental mathematical results fail (being equivalent in ZF to AC or to some weak form of AC). Concerning the theorems mentioned above, the Axiom of Choice turns out to be indeed necessary: In section 4, we construct transitive models of Zermelo-Fraenkel set theory without the Axiom of Choice (ZF) containing a real closed field K, but no integer part of K. In mathematics, the axiom of choice, or AC, is an axiom of set theory equivalent to the statement that the Cartesian product of a collection of non-empty sets is non-empty.It states that for every indexed family of nonempty sets there exists an indexed family of elements such that for every .The axiom of choice was formulated in 1904 by Ernst Zermelo in order to formalize his proof of the well In this article and other discussions of the Axiom of Choice the following abbreviations are common: AC – the Axiom of Choice.

### Comprehensive in its selection of topics and results, this self-contained text examines the relative strengths and the consequences of the axiom of choice. Subjects include consistency and independence, permutation models, and examples and counterexamples of the axiom's use. Each chapter contains several problems and concludes with some historical remarks. 1973 edition.
