SERIAL GROUP RINGS OF FINITE GROUPS. p-NILPOTENCY

摘要

It is proved that if F is an arbitrary field of characteristic p and G is a finite p-nilpotent group with a cyclic p-Sylow subgroup, then the group ring FG is serial. As a corollary, it is shown that for an arbitrary field F of characteristic 2 and any finite group G, the ring FG is serial if and only if the 2-Sylow subgroup of G is cyclic. Bibliography: 21 titles.
