Welcome to the website of the GLEN aka "Highland Cow"
The GLEN is a joint seminar in algebraic geometry between the
Universities of Glasgow, Liverpool, Manchester, Sheffield and
We hold four meetings a year, rotating between the various
participating institutions. Previous meetings can be
maintain a mailing list for related announcements, to join please

Local organizers include Gwyn Bellamy
Pagani (Liverpool), Hendrik Suess
(Manchester) and Evgeny
Shinder (Sheffield). GLEN is coordinated by Johan Martens
GLEN is supported by a Scheme
