Calf is the junior COW.
The principal organiser is Tom Sutherland (Sheffield/Oxford).

The COW seminar has some funds for travel expenses. To make a claim you have to fill in a Bath travel claim form(the word COW should appear prominently) and post it to Finance Secretary, Department of Mathematical Sciences, University of Bath, Bath BA2 7AY.

The next Calf meeting is expected to be in Bath in early May
