Lambda-conductors for group rings
F. J. -B. J. Clauwens
This paper discusses the lambda-ring version of the notion of conductor ideal for the group ring of a finite abelian group. We prove that if the group is primary, the lambda-conduc…

The nilpotence degree of torsion elements in lambda-rings
F. J. -B. J. Clauwens
It is known that any torsion element in a lambda-ring is nilpotent. In this note we deduce a sharp estimate for the nilpotence degree of such an element.
