Aleph number - Wikipedia
In mathematics, particularly in set theory, the aleph numbers are a sequence of numbers used to represent the cardinality (or size) of infinite sets that can be well-ordered. They were introduced by the mathematician Georg Cantor [1] and are named after the symbol he used to denote them, the Hebrew letter aleph (ℵ). [2][a]
Aleph-null | Definition, Transfinite Numbers, Infinity, & Facts ...
Aleph-null (ℵ0), in mathematics, the cardinality of the infinite set of natural numbers {1, 2, 3, …}. The cardinality, or cardinal number, of a set is the number of elements of a set. For example, the number 3 is the cardinality of the set {1, 2, 3} as well as of any set that can be put into a
The aleph numbers, $\aleph_\alpha$ - cantors-attic
The aleph function, denoted ℵ, provides a 1 to 1 correspondence between the ordinal and the cardinal numbers. In fact, it is the only order-isomorphism between the ordinals and cardinals, with respect to membership. It is a strictly monotone ordinal function which can be defined via transfinite recursion in the following manner: ℵ 0 = ω.

2016年2月1日 · According to the book "Set theory, logic and their limitations" by Moshé Machover, aleph is the first letter of the word "einsoph", which is the Hebrew word for infinity, and is also used in cabbalistic traditions as a word for God.
Infinity - Wikipedia
A different form of "infinity" is the ordinal and cardinal infinities of set theory—a system of transfinite numbers first developed by Georg Cantor. In this system, the first transfinite cardinal is aleph-null (ℵ 0), the cardinality of the set of natural numbers.
elementary set theory - Could someone explain aleph numbers ...
Is there an infinite amount of ℵ ℵ numbers or do they stop at some finite number? To understand the ℵ ℵ numbers properly you need to understand the ordinal numbers first, at least a little bit. The idea of an ordinal is to model the notion of a length of a queue to the bathroom in a party.
elementary set theory - The Aleph numbers and infinity in …
What is the difference between infinity as shown by the aleph numbers and the infinity we see in algebra and calculus? Are they interchangeable/transposable in any way? For example, could you describe the infinity of a limit with an aleph number?
