Pure N-high Subgroups, P-adic Topology and Direct Sums of Cyclic Groups
This paper is divided into two sections. In the first, we characterize the subgroups N of a reduced abelian primary group for which all pure N -high subgroups are bounded. This condition on pure N -high subgroups occurs in several instances, for instance, all pure N -high subgroups of a …
