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.
COW welcomes GAeL
GAeL XXV is taking place in Bath, 26th30th June 2017.

Social programme
Lunch in the Common Room both days. Other decisions to be made by those present.

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 an aprèsGAeL meeting in Warwick following on from GAeL XXV in Bath.

Other events
 AprèsGAeL: see above, or the local schedule
 Higher Dimensional Birational Geometry, in honour of Professor Shigefumi Mori, takes place in Warwick on July 14th15th.

Links to future events and related algebraic geometry sites are sometimes collected at a central location.

The northern equivalent of COW is
GLEN,
which meets in Glasgow, Liverpool, Edinburgh and Newcastle.
The midlands equivalent of COW is
EmSG,
which meets in Nottingham, Loughborough, Leicester and Sheffield. Do
not be confused by one of the COW's LMS official supporters being at
Loughborough, nor by EmSG's webpage being in Sydney.

A more local but even less specific seminar is the London Topology and
Geometry Seminar, also known as G&T.

The Calf
is a seminar organised by and for graduate students in geometry.
