Yet Another Proof of Cantor's Theorem
N. Raja · 2008
Abstract: We present various proofs of Cantor’s theorem in set theory: namely that the cardinality of the power set of a set X exceeds the cardinality of X, and in particular the continuum is uncountable. One of the proofs we present is inspired by Yablo’s non-self-referential Liar’s paradox, and it seems to bear a dual relationship to yet another proof.
