Let p be a prime. This paper classifies finite connected reductive groups G in characteristic p with the property that all complex character values of G belong to an unramified above p extension of the field of rational numbers. The main application of these results is to the problem of describing t
## Abstract We characterize preservation of superstability and Οβstability for finite extensions of abelian groups and reduce the general case to the case of __p__βgroups. In particular we study finite extensions of divisible abelian groups. We prove that superstable abelianβbyβfinite groups have o
