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. We maintain a mailing list for
related announcements, to join please email email@example.com.
Local organizers include Gwyn Bellamy
Rizzardo (Liverpool), Hendrik Suess
(Manchester) and Evgeny
Shinder (Sheffield). GLEN is coordinated by Johan Martens
GLEN is supported by a Scheme
3 Grant of the London
Mathematical Society, and the EPSRC Programme Grant
"Enhancing Representation Theory, Noncommutative Algebra And
Geometry Through Moduli, Stability And Deformations". We
maintain a mailing list, please contact Johan Martens if you
wish to join the list or post.
