Behind the scenes: The Furedi - Hajnal conjecture by Adam Marcus I will be talking about the Furedi-Hajnal conjecture, a problem in pattern avoidance in extremal combinatorics. The solution is unusually simple once you see it, but it is not obvious where any of the ideas came from. I will try to go "behind the scenes" and show the process (both successes and failures) that eventually led to a solution.
