摘要
Let G be a locally soluble-by-finite group in which H/H-G has finite (Prufer) rank for all subgroups H of G, where H-G denotes the normal core of H in G. It is proved that G has an abelian normal subgroup A such that G/A has finite rank, that there is an integer r such that H/H-G has rank at most r for all H, and that the rank of G/A is bounded in terms of r. Similar results hold for related classes of groups G.
