Countable Sets and Infinity
WebbIn mathematical terms, a set is countable either if it s finite, or it is infinite and you can find a one-to-one correspondence between the elements of the set and the set of natural … WebbRelevant definitions: “A set that is either finite or has the same cardinality as the set of positive integers is called countable. A set that is not countable is called uncountable. When an infinite set S is countable, we denote the cardinality of S by א0 (where א is aleph, the first letter of the … 7.
