Here are slides for recent talks, in reverse chronological order of delivery. If the date is incomplete, then the slides are not yet available, probably because the talk has not yet been given. Slides for several earlier talks seem no longer to be available. Some talks have small variations in slides and are grouped together; the slide version here is usually the one from the first talk.
