No; Cantor's work on cardinality has nothing to do with Complex
Analysis, And Aleph-1 is not the cardinality unless you assume the
Continuum Hypothesis. Aleph-1 is simply the next cardinal after
Aleph-0. Without the Continuum Hypothesis, the power set of a
countable set might have cardinality greater than Aleph-1.
