Query: Lambda-conductors for group rings   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-conductor is the intersection of the classical conductor
and the augmentation ideal.
