The Lattice of Fully Invariant Subgroups of a Cotorsion Group

Abstract

In this monograph, we discuss some problems of the theory of Abelian groups. In particular, the lattice of fully invariant subgroups of a cotorsion group is studied in detail. The currently available results related to this topic are presented.The purpose of this monograph is to acquaint undergraduates, senior students, and doctoral candidates with the state of the art in this field.
