Isotype separable subgroups of mixed abelian groups

Suppose that H is an isotype subgroup of a global mixed abelian group G and that K is an arbitrary infinite cardinal. If H has a K-cover of almost balanced Pure subgroups, it is shown that H is an almost strongly K-separable subgroup of G. The converse is established in the case when G is a global Warfield group. Our results generalize similar theorems for torsion-free and p-local abelian groups.
