2006 Fields medalist Okounkov's invited lecture series begins on Monday. Ideally only those who registered would come to the first few Okounkov lectures, as the IMS has limited space. Anyone else who wants to come is of course very welcome, but please stand at the back for the first few (oversubscribed) lectures. After that things will thin out and there should be plenty of room. For details, please consult the webpage www.ma.ic.ac.uk (slash) (tilde) rpwt (slash) LMS.html (sorry, triangle server does not allow special characters)
