It is time to register, so **please** do not forget:

This Spring I will be teaching

Topics in set theory.The unofficial name of the course is Combinatorial Set Theory.We will cover diverse topics in combinatorial set theory, depending on time and the interests of the audience, including partition calculus (a generalization of Ramsey theory), cardinal arithmetic, and infinite trees. Time permitting, we can also cover large cardinals, determinacy and infinite games, or cardinal invariants (the study of sizes of sets of reals), among others. I’m open to suggestions for topics, so feel free to email me or to post in the comments.

Prerequisites:Permission by instructor (that is, me).

Recommended background:Knowledge of cardinals and ordinals. A basic course on set theory (like 502: Logic and Set Theory) would be ideal but is not required.

.The course may be cancelled if not enough students enroll, which would make us all rather unhappy, so don’t let this happen
