The gamma filtrations of K-theory of complete flag varieties (1711.04706v2)
Published 13 Nov 2017 in math.AT and math.KT
Abstract: Let G be a simply connected compact Lie group and T its maximal torus. We compute the graded ring gr_{gamma}(G/T) associated with the gamma filtration of the complex K-theory K(G/T). We use the Chow ring of the corresponding versal flag variety.
