COW seminar
The COW seminar is an Algebraic geometry seminar which is so called
because it originally met in Cambridge, Oxford or Warwick. Meetings, of which
there are several every term, are now also regularly held in Bath and London (Imperial College) and
occasionally in other places.
The general organisers are Miles Reid at Warwick
and Gregory Sankaran at
Bath. Many other people help.
The COW seminar is funded by the London
Mathematical Society. The funds are held at Bath. To claim your
travel expenses 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.

Social programme
There is an extensive social programme associated with the BMC.

When a COW meeting is planned, a
copy of the announcement suitable for
printing and displaying on a notice board is made available. This also
carries
abstracts.
Future meetings
There will be a COW event as part of the B(A)MC in Cambridge, 30th
March2nd April 2015. The COW will present four speakers, two on
Monday 30th March and two on Wednesday 1st April. The second of these
sessions forms part of the celebrations of the 150th anniversary of
the London Mathematical Society.
