On Adams operations on the higher K-theory of group rings, 
by Bernhard K\"ock

Using Quillen's universal transformation we verify some (standard) 
properties of Adams operations on the higher K-theory of projective 
modules over group rings. Furthermore, we rather explicitly describe 
Adams operations on the Whitehead group K_1(CG) associated with the 
group ring CG of a finite group G over an algebraically closed field 
C of characteristic 0.
