Abstract

Various problems in modular p-group algebras are solved through extensive study of dimension subgroups. As an application it is shown that, if G is an infinite res-P group (p > 2) and K is a field of characteristic p, then the least upper bound on the numbers of generators of ideals in KG equals the minimal index of a cyclic Subgroup of G.
