21 | After covering the basic axioms, we move on to constructibility and the beginnings of forcing. Our text is Kunen's "Axiomatic Set Theory." | ||
22 | |||
23 | === Prerequisites === | ||
24 | |||
25 | Students should be familiar with the basic theory of cardinal and ordinal numbers, as set out for example in Enderton's "Elements of Set Theory." | ||

49 | p.45, 18. Prove: there is a continuous, strictly increasing cofinal function from cf(alpha) to alpha. (An increasing function f is continuous if f(u) = sup(f(z), z<u) for each limit u.) Prove: f is continuous iff f is continuous in the order topology of ordinals. (I.e. the topology generated by open intervals.) NOTE: STUDENTS DO NOT HAVE TO FINISH THESE BY THE TIME THE EXERCISE CLASS MEETS, BUT THE CLASS WILL BE HELD AND THE EXERCISES WILL BE GONE OVER. | ||
