There will be a series of Leverhulme Lectures by Jon Aaronson (Tel Aviv). None of the talks will assume attendance at the previous (or future) talks. The first will be held on Thursday afternoon (time to be announced) and the second on Friday morning at 11am. The third talk is part of the one day ergodic theory meeting and will be held at 1.15pm on Friday. All three talks will be in room 39AA04. There is no funding (beyond expenses associated to the one day ergodic theory meeting to participating institutions) but we are happy to help with finding accommodation.
