Twisted gamma-filtration of a linear algebraic group
arXiv:1102.0037 · doi:10.1112/S0010437X11007494
Abstract
In the present notes we introduce and study the twisted gamma-filtration on K_0(G), where G is a split simple linear algebraic group over a field of characteristic prime to the order of the center of G. We apply this filtration to construct torsion elements in the gamma-ring of an inner form of the variety of Borel subgroups of G.
