Prove for the following: a. Theorem: (Cantor-Schroder-Bernstein in the 1800s) For any set S, |S| < |P(S)|. b. Proposition N×N is countable. c. Theorem: (Cantor 1873) Q is countable. (Hint: Similar. Prove for positive rationals first. Then just a union.)

Prove that a disjoint union of any finite set and any countably infinite set is countably infinite. Proof: Suppose A is any finite set, B is any countably infinite set, and A and B are disjoint. By definition of disjoint, A ∩ B = ∅ In case A = ∅, then A ∪ B = B, which is countably infinite by hypothesis. Now suppose A ≠ ∅. Then there is a positive integer m so that A has m elements...
