Welcome to the website of the GLEN aka "Highland Cow"
seminar.
The GLEN is a joint seminar in algebraic geometry between the
Universities of Glasgow, Liverpool, Manchester, Sheffield and
Edinburgh.
We hold four meetings a year, rotating between the various
participating institutions. We maintain a mailing list for
related announcements, to join please email johan.martens@ed.ac.uk.
Local organizers include Gwyn Bellamy
(Glasgow), Eleonore Faber
(Leeds), Alice
Rizzardo (Liverpool), Evgeny Shinder
(Sheffield) and Graeme Wilkin
(York). GLEN is coordinated by Johan Martens
(Edinburgh).
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.
