COW Seminar

COW seminar

Meetings - - Algebraic geometry information - - Other events

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 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 après-GAeL meeting in Warwick following on from GAeL XXV in Bath.
