Plenary Sessions

These links point to slidecasts, i.e., presentation slides accompanied by audio of the lectures. Some invited talks and prize lectures aren't included here, for one or more of the following reasons: (1) the speaker didn't give us permission to record and post their presentation, (2) the quality of the recording was substandard, or (3) a technical glitch prevented the successful recording of the audio and/or presentation slides.
