Twisted gamma filtration of a linear algebraic group
Published online by Cambridge University Press: 25 July 2012
Abstract
In the present paper we introduce and study the twisted γ-filtration on K0(Gs), where Gs is a split simple linear algebraic group over a field k of characteristic prime to the order of the center of Gs. We apply this filtration to construct nontrivial torsion elements in γ-rings of twisted flag varieties.
