Inductively define a sequence (Cn) ( C n) of subsets of A A by C0 = A∖B C 0 = A ∖ B and Cn+1 = f(Cn) C n + 1 = f ( C n) .
This is a useful feature in the ordering of cardinal numbers . The theorem is named after Felix Bernstein and Ernst Schröder. It is also known as Cantor–Bernstein theorem, or Cantor–Schröder–Bernstein, after Georg Cantor who first published it without proof.
