Cardinal Arithmetic for Skeptics

  title={Cardinal Arithmetic for Skeptics},
  author={Saharon Shelah},
When modern set theory is applied to conventional mathematical problems, it has a disconcerting tendency to produce independence results rather than theorems in the usual sense. The resulting preoccupation with “consistency” rather than “truth” may be felt to give the subject an air of unreality. Even elementary questions about the basic arithmetical operations of exponentiation in the context of infinite cardinalities, like the value of 2א0 , cannot be settled on the basis of the usual axioms… CONTINUE READING
