In mathematics, transfinite numbers are numbers that are "infinite" in the sense that they are larger than all finite numbers, yet not necessarily absolutely infinite. These include the transfinite cardinals, which are cardinal numbers used to quantify the size of infinite sets, and the transfinite ordinals, which are ordinal numbers used to provide an ordering of infinite sets. The term transfinite was coined by Georg Cantor in 1895, who wished to avoid some of the implications of the word i… WebTransfinite numbers are used to describe the cardinalities of "higher & higher" infinities. cardinality of countably infinite sets. cardinality of the "lowest" uncountably infinite sets; also known as "cardinality of the continuum". cardinality of the next uncountably infinite sets From this we see that .

WebIn fact, one cannot prove that any infinite set exists: the hereditarily-finite sets constitute a model of ZF without Infinity. This bothers me quite a bit for the following reason.

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.
