Together with Laurence Lasselle I am running a series of Training Seminars for PhD students in the academic year 2008/09 in St. Andrews. Lectures are given by Robert Campbell, Ralf Korn, Marc Yor, Thomas Lux, Pierre Cartigny, Olaf Menkens, Rod McCrorie, Evelyn Buckwar and Elisa Alos. This series has closed now, videos and slides of all lectures are now available at Videos and Slides
