Smallest infinite cardinal number
WebbIf the axiom of choice (AC) is used, it can be further proved that the class of cardinal numbers is totally ordered, and thus is the second-smallest infinite cardinal number. Using AC we can show one of the most useful properties of the set ω1: any countable subset of ω1 has an upper bound in ω1. WebbAleph null:- The smallest Aleph defined as the cardinality of the positive integers, and also that of the rationals and of the algebraic numbers, but not of the reals. The usual symbol is the Hebrew letter subscript 0. Aleph:- Any infinite Cardinal number, usually denoted by the Hebrew letter Aleph.
