Alephs, Cofinality, and the Axiom of Choice

  • Abhijit Dasgupta


This chapter concludes our development of cardinals and ordinals. We introduce the first uncountable ordinal, the alephs and their arithmetic, Hartogs’ construction, Zermelo’s well-ordering theorem, the comparability theorem for cardinals, cofinality and regular, singular, and inaccessible cardinals, and the Continuum Hypothesis.
