Continuum (set theory), the
real line or the corresponding cardinal number •
Linear continuum, any ordered set that shares certain properties of the real line •
Continuum (topology), a nonempty compact connected
metric space (sometimes a
Hausdorff space) •
Continuum hypothesis, a conjecture of Georg Cantor that there is no cardinal number between that of countably infinite sets and the cardinality of the set of all real numbers. The latter cardinality is equal to the cardinality of the set of all subsets of a countably infinite set. •
Cardinality of the continuum, a cardinal number that represents the size of the set of real numbers == See also ==
