On the K-theory of the flag variety.
Friday 11th August, 12-1pm, Carslaw 275.I shall discuss the structure of the the (T-equivariant) K theory of a (generalized) flag variety and its relation to the affine Hecke algebra. This relationship can be exploited to derive a K theoretic analogue of the classical Pieri-Chevalley formula in the cohomology of the flag variety. Amazingly, this geometry is modeled by the combinatorics of the Littelmann path model.
