Calf Seminar

Calf is the junior COW. Announcements are made using the COW mailing list.

The Calf has moved on to pastures new. The current Calf web page can be found here.

This page is being maintained as a record of those Calf events organised between October 2003 and October 2005.

The principal organisers were Alexander Kasprzyk (Bath) and Elizabeth Baldwin (Oxford).

Local organisers included Anne-Sophie Kaloghiros (Cambridge), Ed Segal (Imperial), Kyriakos Papadopoulos (Liverpool), and James Smith (Warwick).
