Definition Of A Countable Set
Definition Of A Countable Set. The set of algebraic numbers is countable, let lk denote the set of algebraic numbers that satisfy polynomials of the form c0+c1x+.+cnxn where n < k and max(|cj|) < k. Z !n as follows :
• the elements of the set can be enumerated and listed. If the isomorphism is stated explicitly then the set is called a counted set or an enumeration. A set is called countable, if it is finite or countably infinite.
