There will be a meal in a local restaurant afterwards (early, so that people can catch trains). Everyone is invited, the speakers go free! Please let Brigitte Calderon (b.calderon@reading.ac.uk) know beforehand if you wish to come, so that I can tell the restaurant how many to expect.

I acknowledge with thanks the help provided by the Mathematics and Statistics Department at Reading, and the continuing support of the BCC.                                                                                                                              Anthony Hilton
