Web13 de fev. de 2013 · Two countably infinite sets A and B are considered to have the same "size" (or cardinality) because you can pair each element in A with one and only one element in B so that no elements in either set are left over.

WebWhat kind of operation — and number — becomes possible by constructing quaternions and octonions? The hierarchy of the cardinalities of these sets is # N = # Z = # Q < # R = # C. How are # H and # O inserted in it? Can yet another number set be constructed from O? Web𝒫 ( N) contains infinite subsets of N, e.g. the set of all even numbers {2, 4, 6,...}, as well as the empty set . Now that we have an idea of what the elements of 𝒫 ( N) look like, let us attempt to pair off each element of N with each element of 𝒫 ( N) to show that these infinite sets are equinumerous.

WebIn particular, in ZFC using the Replacement axiom in the form of transfinite recursion, there are huge uncountable sets of different infinite cardinalities. The infinities ℵα, for example, are defined by transfinite recursion: ℵ0 is the first infinite cardinality, or ω. ℵα + 1 is the next (well-ordered) cardinal after ℵα.
