Web5 sep. 2024 · What Cantor’s theorem says is that this always works. If A is any set, and P ( A) is its power set then A < P ( A) . In a way, this more general theorem is easier to prove than the specific case we just handled. Theorem 8.3. 1: Cantor. For all sets A, A is not equivalent to P ( A).
