Extremal Combinatorics
The name "extremal combinatorics" covers many of the most significant discrete developments of recent (and less recent) years, and many of the most interesting open problems. We'll sample some of these, trying to emphasize the wide range of ideas, methods and extra-combinatorial machinery that come into play.

Apart from basic combinatorics, I'll try to make the course "self-contained," meaning some maturity will help but we'll fill in background as needed. Check with me if in doubt.
