Axiom of Choice, a group of Persian immigrants now living in California, are here to remind us that for those who lived through it, that first month of 1991 was cataclysmic - the culmination of more than a decade of senseless bloodshed in the region.
The axiom of choice is an axiom in set theory with wide-reaching and sometimes counterintuitive consequences. It states that for any collection of sets, one can construct a new set containing an element from each set in the original collection. In other words, one …
The Axiom of Choice and Cardinal Arithmetic The Axiom of Choice Axiom of Choice (AC).Every family of nonempty sets has a choice func-tion. If S is a family of sets and ∅∈/ S,thenachoice function for S is a func- tion f on S such that (5.1) f(X) ∈X for every X ∈S. The Axiom of Choice postulates that for every S such that ∅∈/ S there exists a function f on S that satisfies (5.1). How I Learned to Stop Worrying and Love the Axiom of Choice. The universe can be very a strange place without choice.

In mathematics, the axiom of choice, or AC, is an axiom of set theory equivalent to the statement that a Cartesian product of a collection of non-empty sets is non-empty. The principle of set theory known as the Axiom of Choice has been hailed as “probably the most interesting and, in spite of its late appearance, the most discussed axiom of mathematics, second only to Euclid’s axiom of parallels which was introduced more than two thousand years ago” (Fraenkel, Bar-Hillel & Levy 1973, §II.4). Axiom of Choice An important and fundamental axiom in set theory sometimes called Zermelo's axiom of choice. It was formulated by Zermelo in 1904 and states that, given any set of mutually disjoint nonempty sets, there exists at least one set that contains exactly one element in common with each of the nonempty sets.

The Axiom of Choice states that for any family of nonempty disjoint sets, there exists a set that consists of exactly one element from each element of the family. It seems strange at first that such an innocuous sounding idea can be so powerful

For finite sets C, a choice function can be constructed without appealing to the axiom of choice.In particular, if C = ∅, then the choice function is clear: it is the empty set!It is only for infinite (and usually uncountable) sets C that the existence of a choice function becomes an issue. Here one can see why it is not considered “obvious” and always taken for an axiom by everyone: one

AC, the axiom of choice, because of its non-constructive character, is the most controversial mathematical axiom, shunned by some, used indiscriminately by others. 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). Axiom of Choice).

- Given any nonempty set Y whose members are pairwise disjoint sets, there exists a set X consisting of exactly one element taken Zermelo-Fraenkel set theory. It is denoted ZF and contains 8 axioms.
