Alephs
Alephs are a set of infinite cardinal numbers used in set theory to describe the size of infinite sets. The term "aleph" is derived from the Hebrew letter aleph (א), which is the first letter of the Hebrew alphabet. The smallest infinite cardinal number is denoted by aleph-null (ℵ0), which represents the cardinality of the set of natural numbers. This is the smallest infinite cardinal number, and it is also the cardinality of the set of integers, rational numbers, and algebraic numbers.
The next infinite cardinal number is aleph-one (ℵ1), which is the cardinality of the set of real
Alephs are used to describe the size of infinite sets in a way that is independent of
Alephs are also used to describe the size of infinite sets that are not countable. For example,
In summary, alephs are a set of infinite cardinal numbers used in set theory to describe the
