WebA set is called countable, if it is finite or countably infinite. Thus the sets are countable, but the sets are uncountable. The cardinality of the set of natural numbers is denoted (pronounced aleph null): Any subset of a countable set is countable. Any infinite subset of a countably infinite set is countably infinite. Let and be countable sets. WebCartesian product We can make a “larger” vector space from two vector spaces X and Y (having a common ﬁeld F) by forming the Cartesian product of X and Y, ... Deﬁnition.
