In January/February 2013 Mike Freedman gave a series of 12 lectures at UC Santa Barbara explaining his proof of the 4-dimensional Poincaré conjecture. The lectures were broadcast live to the Max Planck Institute for Mathematics in Bonn as part of the Semester on 4-manifolds and their combinatorial invariants. Videos of the lectures are available here.
In addition to the videos, I have been typing up some lecture notes. The first, incomplete (!) draft of these notes is currently being revised and completed by a group of people at the Max Planck Institute dubbed "Team Freedman" by Bob Edwards. Bob Edwards and Peter Teichner are volunteering as the official coaches of Team Freedman. I will post occasional updates and keep a change log here.
