Since the cool
cats conference in Canada, I have been catching a few more Oxford
seminars. Yesterday, Andrew Dancer
spoke about Frenkel's
loop group version
of the Langlands
Correspondence. He noted the category theorists in the audience, promising to discuss some category theory, but of course there was very little category theory and I only obtained the usual miniscule improvement in my understanding of this subject.
Meanwhile, I'm off to a lovely old college for lunch and it's a (relatively unusually) beautiful day here!
