Twisted gamma-filtration of a linear algebraic group, by Kirill Zainoulline

In the present notes we introduce and study the twisted gamma-filtration on Grothendieck's K_0 of a split simple linear algebraic group G over a field k of characteristic prime to the order of the center of G. As an application we provide a uniform low bound for the torsion part of the gamma-ring of some twisted flag varieties.
