CalTitle1: Algebra Seminar: Parkinson -- Path combinatorics in loop groups

Auth: anthonyh@asti.maths.usyd.edu.au

In this talk we discuss some joint work with Arun Ram on the
combinatorics of the loop group G=G(k((t))), where
G(.) is a Kac-Moody-Tits group functor.
The points of the affine flag variety G/I
(with I an Iwahori subgroup) can be indexed by generalised
labeled Littelmann paths, which control various double coset
decompositions of G.
In the case when After the seminar we will take the speaker to lunch. See the Algebra Seminar web page for information about other seminars in the series. Anthony Henderson anthonyh@maths.usyd.edu.au. |
